Question
In each of the following number series, one term is wrong. Find the wrong term. 3, 10, 26, 58, 130, 272
Solution
ATQ, Check for multiplication + addition pattern: From 3 to 10: 3 × 2 + 4 = 6 + 4 = 10 From 10 to 26: 10 × 2 + 6 = 20 + 6 = 26 From 26 to next (should be): 26 × 2 + 8 = 52 + 8 = 60 From 60 to next: 60 × 2 + 10 = 120 + 10 = 130 From 130 to next: 130 × 2 + 12 = 260 + 12 = 272 So the pattern is: Multiply by 2 and add even numbers increasing by 2: +4, +6, +8, +10, +12 Correct series: 3, 10, 26, 60, 130, 272 Given series has 58 instead of 60. Therefore, 58 is the wrong term.
