Grab a mug, tshirt, and more at the official site for merchandise: Mind Your Decisions at Teespring. Since the running total can also get to the answer of 96 when extending the pattern to missing lines, many believe that 96 is the answer that makes the most sense. My Books (US and worldwide links) https://mindyourdecisions.com/blog/my-books. Abbiamo un'equazione fratta: tutto si riduce a fare attenzione, non c'è niente di complicato: prima di tutto vediamo le condizioni di esistenza: i denominatori non possono mai annullarsi, quindi x^2-x≠0 ossia x(x-1)≠0 ossia x≠0 e x≠+1. Assuming the formula is true up to line n, we then consider the next line. A mathematician might take a literal approach. Most YouTube channels of my size have a staff of 5 people with a large budget and sponsors. Use step-by-step calculators for chemistry, calculus, algebra, trigonometry, equation solving, basic math and more. That is: 1 + 4 means 1 + 1(4) = 5 2 + 5 means 2 + 2(5) = 12 3 + 6 means 3 + 3(6) = 21. Any number is the correct solution. Dan Munchie, you want to try reverse proof? I send the newsletter to for book releases and other big news. The Correct Answer Explained, Keep reading for a text explanation. MindYourDecisions now has over 1,000 free articles with no ads thanks to community support! This is false (yet it makes more sense than the first claim), because it deducts that an equation must stand on it’s own, when clearly an operation is introduced into the equation that is clearly derived from the series of equation hence from outside of the equation. However, the assumption that the 4th equation should use base 3 does not seem appropriate – it should be a function of the information provided. 1 e 2 sono i due numeri iniziali arbitrari della serie, o, se vogliamo, 2 = 1*2. This is just as legitimate an answer, the assumed form of the unknown equation is just as arbitrary as a+ab. (2/4) Non so se hai capito il … Lines 2 and 3 are valid number sentences and equations, that happen to be false. For example, 1 + 4 is turned into 2 + 5; so both the numbers 1 and 4 are increased by 1. Answer: 45 Explanation 1: 1+4 = 4x1 + 1 = 5 2+5 = 5x2 + 2 = 12 3+6 = 6x3 + 3 =21 The logic here is : Multiply the two digits on left-side and to this product add the first number on the LHS. Università. But some people interpreted the problem differently and arrived at a different answer. Since 2007, I have devoted my life to sharing the joy of game theory and mathematics. It's been quite a journey! Please check your local Amazon website for availability and program terms. Art. My solution is different though: c = (a * (2a + 3)) – (a^ – a) (or if you prefer a more proper ^ squared expression) c = (a * (2a + 3)) – (a^2 – a), a + b = c b = a + 3 (this is our only constant in the series, therefore dictates the series progression). Hopefully it does make sense, and hopefully I’m not wrong. YouTube Video – Can You Solve Amazon’s Hanging Cable Interview Question? 1 5 1 3 2/3 x (di) 2/5 = 4/15 2/5 x (di) 2/3 = 4/15 3/3 x 5/5 = 15/15. Unfortunately, [base0] cannot exist. I think that the pattern is: Numbers on the left are decimal values Numbers on the right are expressed in the sequence: base 6 for the first line then base 5 for the second line, then base 4, then base 3 Thus 1+ 4 = 5 (base 6 2+5 = 12 (base 5 3+6 = 21 (base 4 8+11 = 201 (base 3 If my conversion of 19(decimal) to base 3 is wrong, please correct the 201 number and make the corrected value to be my solution to the puzzle. Both the 40 and 96 answers make assumptions that really aren’t justified. (a+b)[base10] = (a+(a+3))[base10] = f(a)[base10] = f(a)[base(7-a)]. 1 + 4 = 5 2 + 5 = 12 3 + 6 = 21 8 + 11 = ??? Se è 1 il numero di sopra il risultato è quello. If we treat the puzzle as the object, then we may want to look for the “simplest” explanation for the pattern. (rated 4.6/5 stars on 12 reviews). I get so many emails that I may not reply, but I save all suggestions for puzzles/video topics. In the next line n + 1, we add the numbers (n + 1) + (n + 4). 2. In general, line n has the equation n + (n + 3), which is equal to the result n + n(n + 3) = n(n + 4). Calculation: 1/2 + 2/3 + 5/4 - fraction calculator. This solution does not assume any ulterior rules. It came out to be a surprisingly concise equation with nice whole numbers. 4-5 Abram partì dalla località di The answer of 40 inducts something that isn’t explicitly stated in any individual line, therefore must also be rejected. "All will be well if you use your mind for your decisions, and mind only your decisions." The assumption that a+b equals and only equals a+ab is the error. So if you found this pattern, then you’re part of a special 1 in 500,000 group! 2 = 5 / 10 + 2 / 10 = 5 + 2 / 10 = 7 / 10 For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. @Gregory Bramwell: I am curious about other patterns and glad you left this comment as I had not come across this interpretation before. Espressioni numeriche svolte passo passo, con numeri interi, frazioni, numeri decimali, periodici e non, numeri relativi, per la secondaria di primo grado (ex scuola media) e per il … You’re all grossly over complicating it.
