Question
In each of the following number series, one term is
wrong. Find the WRONG term. 5, 10, 19, 33, 49, 70Solution
Differences: 10 − 5 = 5 19 − 10 = 9 33 − 19 = 14 49 − 33 = 16 70 − 49 = 21 Try differences increasing by 4: 5, 9, 13, 17, 21 Start from 5: 5 → 10 (+5) 10 → 19 (+9) 19 → 32 (+13) 32 → 49 (+17) 49 → 70 (+21) So the correct term should be 32, not 33. Wrong term = 33
