Missing Number in the Series
The given series is: 1, 5, 13, 25, 41, ?

Pattern in the Series
To find the missing number in the series, let's look for a pattern:
1 + 4 = 5
5 + 8 = 13
13 + 12 = 25
25 + 16 = 41
From the pattern above, we can see that the differences between consecutive numbers are increasing by 4, 8, 12, 16, and so on.

Finding the Missing Number
To find the next number in the series, we need to add 20 to the last number:
41 + 20 = 61
Therefore, the missing number in the series is 61, which corresponds to option 'C'.
