Just substitute in values for n:
Sn: 2 is a factor of n^2+7n
S1: 2 is a factor or 1^2+7*1
S2: 2 is a factor of 2^2+7*2
S3: 2 is a factor of 3^2+7*3
Now just show that each is true.
A statement Sn about the positive integers is given. Write statements S1, S2, and S3, and show that each of these statements is true.
Sn: 2 is a factor of n2 + 7n
