Answer 1

The pattern in this series seems to be alternating between

subtracting one and then adding two.

22 - 1 = 21,

21 + 2 = 23,

23 - 1 = 22,

22 + 2 = 24,

24 - 1 = 23,

Following this pattern, the next operation would be to add two.

So, 23 + 2 = 25.

Therefore, the missing term in the series should be 25. So, the

correct answer is 3) 25.
