N-th Number Sequence Help

So the question is:
''The n-th term of a number sequence is n^2 + 1 ('n' squared plus one)
Write down the first three numbers of the sequence''
Need the answer and workings please.
Thanks in Advance.

f(n) = n^2 + 1

f(1) = 1^2 + 1 = 1 + 1 = 2
f(2) = 2^2 + 1 = 4 + 1 = 5
f(3) = 3^2 + 1 = 9 + 1 = 10

Hope this helps!

f(n)=n^2+1

f(1)=1^2+1
f(1)=(1x1)+1
f(1)=1+1
f(1)=2

f(2)=2^2+1
f(2)=(2x2)+1
f(2)=4+1
f(2)=5

f(3)=3^2+1
f(3)=(3x3)+1
f(3)=9+1
f(3)=10
