Question
In the following number series, a wrong number is
given: 2, 6, 16, 38, 84, 168, 368, 750 The wrong number is:Solution
The pattern in the given number series follows a specific multiplication and addition rule. Let's break it down: 1. (2 × 2) + 2 = 6 2. (2 × 6) + 4 = 16 3. (2 × 16) + 6 = 38 4. (2 × 38) + 8 = 84 5. (2 × 84) + 10 = 178 (This is where the pattern breaks) 6. (2 × 178) + 12 = 368 7. (2 × 368) + 14 = 750 According to the pattern, the number 168 should be replaced with 178. Hence, the wrong number in the series is 168.
