10-8.
1. 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 ✎

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

2. Write a formula for the nth term of the sequence for this situation.

3. How much money would have been in the account on Angela’s first birthday, just after Uncle Zachary made his 12th 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) = 5n + 45
