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.

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
