Solution

The given series is 3, 5, 13, 43, 176, 891, 5353.

The pattern in the series seems to be that each number is multiplied by a certain number to get the next number.

Let's try to find the pattern:

3 * 2 - 1 = 5 5 * 2 + 3 = 13 13 * 3 + 4 = 43 43 * 4 + 5 = 177

Here, we see a discrepancy. The fourth operation should have resulted in 177, but the number given in the series is 176.

So, the wrong number in the series is 176.
