Grimmjow:
3109 is the answer
Give reason please
5^2 - 2 = 25 - 2 = 23 and 5^3 - 2^2 = 125 - 4 = 121 and 5^4 - 2^3 = 625 - 8 = 617 and 5^5 - 2^4 = 3125 - 16 = 3109

Hi there!
Here's the answer:
•°•°•°•°•°•<><><<><>><><>°•°•°•°•°•°
5 23 121 617 _?_
The given series is of the form:
i term in the series = [5^i] - [2^(i-1)]
where i > 2
•°•°•°•°•°•<><><<><>><><>°•°•°•°•°•°
I term: 5
II term: 5² - 2 = 25 - 2 = 23
III term: 5³ - 2² = 125 - 4 = 121
IV term: 5⁴ - 2³ = 625 - 8 = 617
V term: (5^5) - 2⁴
i.e., 3125 - 16 = 3109
•°•°•°•°•°•<><><<><>><><>°•°•°•°•°•°
•°• Next No. in the series = 3109
