Answer 2

Answer:

The wrong number in the given number series is 14

Step-by-step explanation:

Given the number series 28, 77, 14, 24, 6, 7, 3

The logic of the number series is as follows

$~~~28~~~~~~~~ 77~~~~~~~~~ \underline{14}~~~~~~~~~~ 24~~~~~~~~~~ 6~~~~~~~~~~ 7~~~~~~~~~~ 3\\2^{5} -4~~~~3^{4} -4~~~~2^{4} -3} ~~~~3^{3} -3~~~~2^{3} -2~~~~3^{2} -2~~~~2^{2} -1$

From the right side, starting with 1, the difference is increased by 1. And it is repeated twice.

Base number starting with 2, alternately taken 2 and 3.

And the powers started with 2, repeated again and then increased by 1. Again 3 is repeated.  

If the same logic is followed, then 3 should be increased by 1.

And hence, $2^{4} -3=16-3=13$

The result is 13, but the number given there is 14.

Therefore, 14 is the wrong number in the given number series.
