Answer 2

The missing number in the series 11, 19, ..., 41, 55 is 29

Solution:

Given, series is 11, 19, ? , 41, 55.

We have to find the missing number.

Let the missing number be n.

If we observe, 19 – 11 = 8 and 55 – 41 = 14.

So, if n – 19 = 10 and 41 – n = 12. Then, it would form an well ordered series.

Let us find the missing number using above logic, if we have the same number in options, then our logic is right, or we have to search for another logic,

Now, according to our logic, x – 19 = 10 → x = 10 + 19 = 29.

We have option b as 29. So our logic is right.

Hence, the missing number is 29.
