Question
In each of the following, one term is wrong. Find the WRONG term. 5, 8, 13, 20, 29, 41
Solution
Differences: 8 − 5 = 3 13 − 8 = 5 20 − 13 = 7 29 − 20 = 9 41 − 29 = 12 Pattern should be consecutive odd numbers: 3, 5, 7, 9, 11, … Last difference should be 11, so last term should be 29 + 11 = 40. 41 is wrong.
