10-7.

Uncle Zachary decided to increase the amount he was saving for Angela by $5 each month instead of three.

How much would he deposit on the month of her second birthday? Homework Help ✎

Write a formula for the

*n*^{th}term of this sequence.How much money is in the account the month of her first birthday, just after he 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.
