1. Consider the sequence - 8, - 5, - 2, 1, 4, ...

D) Find the iterative rule for the sequence.

e) Find the tenth term in the sequence.

An = a1 plus d (n - 1)

its the arithmetic sequence formula

a1 = first term in the sequence

d = the difference which you can find by subtracting - 5 from - 8 = 3

to find the 10th term in the sequence substitute n for 10

a10 = - 8 + 3 (10 - 1)

a10 = - 8 + 3 (9)

a10 = 19
