This is an arithmetic sequence also known as a linear relationship. The rule is 3n+2 for any n terms. So the first term will be n= 1. Substitute and simplify.
3(1) + 2 = 3+2 = 5
Repeat for n= 2.
3(2) + 2 =6+2 = 8
Repeat for n= 3
3(3)+2 = 9+2 = 11
So the first terms in the sequence are 5, 8, and 11.
Part B
The tenth term is when n=10. Substitute and simplify.
