6-5.

Given the sequence $7, 11, 15, 19$, …

1. What kind of sequence is it?

How do you get from one term to the next?
See the online help for problem 5-67. Remember that $t\left(n\right) = mn + t\left(0\right)$.
• Let $t\left(n\right) = 109$ in the equation you wrote for part (b).
Solve for $n$. Remember that $n$ is the term number.
• $n = 26.5$, so no, $109$ is not a term in the sequence.
