If the inputs are: 1, 2, 3, 4, 5 and my outputs are: 1, 5, 11, 19, 29, what is the rule?

Ms. Sue,
Starting with 4, each succeeding output is increased by the next even number.

Blue Ting Ting,
I'm sorry. I'm only in 6th grade though, so I don't know what you mean when you say that.

Math 
Ms. Sue,
1 + 4 = 5
5 + 6 = 11
11 + 8 = 19
10 + 10 = 29

Praphul,
1^2 + 0 = 1
2^2 + 1 = 5
3^2 + 2 = 11
4^2 + 3 = 19
5^2 + 4 = 29
