Determine whether the following set of numbers is part of an arithmetic or geometric sequence. In the space provided, type arithmetic or geometric as your answer. - 2, 4, - 8, 16, ...

Step-by-step explanation:

It's geometric.

You are starting with - 2 and multiplying each successive term by - 2

r = - 2

a1 = - 2

tn = ar^ (n - 1)

So to try it out, let n be the 4th term

t4 = - 2 * (-2) ^ (4 - 1)

t4 = - 2 * (-2) ^3

t4 = - 2 * - 8

t4 = 16 just as the series indicated.
