According to the problem:

when n = 1, the answer is 1

when  n = 2, the answer is 4

when  n = 3, the answer is 9

when  n = 4, the anser is 16, etc.

Try each of the possibilities:

n = 1   --->   2n = 2   --->   n + 3  =  4   --->   n² + 1  =  2   --->   n² = 1

n = 2   --->   2n = 4   --->   n + 3  =  5   --->   n² + 1  =  5   --->   n² = 4

Which one works?
