Solution
The correct option is A 9
Starting from the right,
25 - 4 = 21
21 - 4 = 17
71 - 4 = 13
Each preceding term is 4 less than the succeeding term.
So, the missing term is:
13 - 4 = 9
Starting from the right,
25 - 4 = 21
21 - 4 = 17
71 - 4 = 13
Each preceding term is 4 less than the succeeding term.
So, the missing term is:
13 - 4 = 9
