8 9 17 26 90 ?
The difference between 8 and 9 is "1" which is 1^2.
The difference between 9 and 17 is "8" which is 2^3.
The difference between 17 and 26 is "9" which is 3^2.
The difference between 26 and 90 is "64" which is 4^3.
Then the answer is 5^2 which is "25".

8 × 3 = 24,
24 ÷ 2 = 12,
12 × 3 = 36,
36 ÷ 2 = 18,
18 × 3 = 54,
54 ÷ 2 = 27.
24 ÷ 2 = 12,
12 × 3 = 36,
36 ÷ 2 = 18,
18 × 3 = 54,
54 ÷ 2 = 27.

8*3=24 12*2=24
12*3=36 18*2=36
18*3=54 x*2 = 54.
i.e, x=54/2 = 27.
12*3=36 18*2=36
18*3=54 x*2 = 54.
i.e, x=54/2 = 27.

It's 30.
On each Row,
7mod(1st column +2nd column) = 7mod(3rd column),
For 1st row, 7 mod(6+8)=7 mod(7),
For 2nd row, 7 mod (3+64)=7 mod(4),
For 3rd row, 7 mod(24+48)=7 mod(30).
