Answer:
1/36
Explanation:
If you write the first number as a fraction also, 1/1, then every term has a 1 on top of a fraction.
The denominators (number on the bottom) are
1, 4, 9, 16, 25, this is a list of perfect squares. That is
1 = 1×1 = 1^2
4 = 2×2 = 2^2
9 = 3×3 = 3^2
16 = 4×4 = 4^2
25 = 5×5 = 5^2
So the next number is
6×6 = 6^2
= 36
36 is on the bottom. 1 is on the top.
The next number is 1/36.
