25, 36, 49, 64....

5^2, 6^2, 7^2, 8^2......

so at nth term, it is (n+4)^2

100th term = (100+4)^2 = 104^2 = 10816
Series: 25, 36, 49, 64 .......
Patter: 5², 6², 7², 8² ....

Here, a =  (n + 4)²
Where, n = Any Natural number.

So, a(100) = (100 + 4)²
a(100) = 104 * 104 = 10816

In short, Your Answer would be: 10816

Hope this helps!
