Directions (8-12): Find the wrong term in the following number series....
Given number series: 5, 25, 129, 780, 5441, 43529

To find the wrong term in the given series, we need to identify the pattern or rule followed by the numbers.

Pattern:


  • The first term is multiplied by 5 and then 4 is added to get the second term: 5 × 5 + 4 = 25

  • The second term is multiplied by 5 and then 4 is added to get the third term: 25 × 5 + 4 = 129

  • The third term is multiplied by 5 and then 4 is added to get the fourth term: 129 × 5 + 4 = 780

  • The fourth term is multiplied by 5 and then 4 is added to get the fifth term: 780 × 5 + 4 = 5441

  • The fifth term is multiplied by 5 and then 4 is added to get the sixth term: 5441 × 5 + 4 = 43529

  • Following the same pattern, the next term should be calculated as 43529 × 5 + 4 = 217649


Therefore, the wrong term in the series is 43529. The correct term should be 217649.

Thus, the correct answer is option 'D'.
