A statement Sn about the positive integers is given. Write statements S1, S2, and S3, and show that each of these statements is true. Show your work.

Question

Sn: 2+5+8+...+(3n-1)=n(1+3n)/2

Answer 1

Sn = n(1+3n)/2

Therefore,
S1: 2 = 1(1 + 3(1))/2
S2: 2+5 = 2(1 + 3(2))/2
S3: 2+5+8 = 3(1 + 3(3))/2
They are all true/equivalent for S1, S2, and S3.

Answer 2

can you show me how you got those answers cause i have to show my work THANK YOU

Answer 3
