10-8.

What if Uncle Zachary (from problem 10‑1) had increased the amount he was saving for Angela by $5 each month instead of $3? Homework Help ✎

How much would Uncle Zachary have deposited on Angela’s second birthday?

Write a formula for the

*n*^{th}term of the sequence for this situation.How much money would have been in the account on Angela’s first birthday, just after Uncle Zachary made his 12

^{th}deposit?

Recall that Uncle Zachary puts $50 in Angela's account the first month.

In this case he will put $55 in Angela's account the second month and $60 the third month.

The sequence is 50, 55, 60, 65, ..., which is linear. The equation should be of the form *an* + *b*.

*t*(*n*) = 50 +5(*n* − 1) or *t*(*n*) = 5*n* + 45

Add the first 12 terms of your sequence.
