It's easier to see this way.
input is 1 output is 2
input is 2 output is 5
input is 3 output is 10
input is 4 output is 17
input is 5 output is 26
Do you see the pattern?
Think squares. 
okay but what woulde be the rule

What do you think the rule is?

idk that is why i asked i have been up for 2 hrs trying to figure it out

The input is squared and 1 added to make the output.
1^2 + 1 = 2
2^2 + 1 = 5
3^2 + 1 = 10
