Question
In each of the following number series, one term is wrong. Find the WRONG term. 3, 8, 18, 40, 78, 158
Solution
Check pattern: 3 → 8 = 3 × 2 + 2 8 → 18 = 8 × 2 + 2 18 → ? should be 18 × 2 + 2 = 38, but the term is 40 (wrong) If we put 38 instead of 40: 38 → 78 = 38 × 2 + 2 78 → 158 = 78 × 2 + 2 So the term not following the pattern “previous term × 2 + 2” is 40. Wrong term = 40
