Question
Find the wrong number in the given number series.
3, 8, 26, 102, 398, 1639Solution
ATQ,
Each term: previous × 4 - a number increasing by 2
3 × 4 - 4 = 8
8 × 4 - 6 = 26
26 × 4 - 8 = 102
102 × 4 - 10 = 398
398 × 4 - 12 = 1580 ← Should be 1580, not 1639
So the correct number is 1580, and Wrong number is: 1639
