Question
n each of the following questions a number/letter series is given.Which one of the alternatives will replace the question mark (?)1. 11, 29, 55, ?, 131(A) 110 (B) 81(C) 89 (D) 78
Solution
To find the missing number in the given series, let's analyze the pattern:
The difference between the first two numbers is 29 - 11 = 18. The difference between the second and third numbers is 55 - 29 = 26. The difference between the third and fourth numbers is 131 - 55 = 76.
We can observe that the differences are increasing by 8 each time. Therefore, we can find the missing number by adding 8 to the last number in the series.
131 + 8 = 139
So, the missing number is 139.
None of the given alternatives (A) 110, (B) 81, (C) 89, or (D) 78 match the correct answer.
