2 + (1^2 - 1) = 2,
2 + (2^2 - 1) = 5,
5 + (3^2 - 1) = 13,
13 + (4^2 - 1) = 28,
Same procedure as follows we get,
28 + (5^2 - 1) = 52
The next term is 52.
2 + (2^2 - 1) = 5,
5 + (3^2 - 1) = 13,
13 + (4^2 - 1) = 28,
Same procedure as follows we get,
28 + (5^2 - 1) = 52
The next term is 52.

2-2=0
2-5=3
5-13=8
13-28=15.
The difference between 3&8=5, 8&15=7, and the difference in 5&7=2 got 9 then add 9+15=24.
Add 24+28=52.
2-5=3
5-13=8
13-28=15.
