6-10.

Given the sequence 7, 11, 15, 19, …. Homework Help ✎

What kind of sequence is it?

Write an explicit equation for the sequence.

Is 109 a term of the sequence? If so, which term is it?

How do you get from one term to the next?

By adding or by multiplying?

See the online help for problem 5-68. Remember that *t*(*n*) = *mn* + *t*(0).

Let *t*(*n*) = 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.
