Question

Find an equation for the nth term of the sequence.

-3, -12, -48, -192

Answer 1

i realized that you are learning recursive. so base case is -3, and recursive case is 4 * previous case.

Answer 2

an = 4 • -3n + 1

an = -3 • 4n

an = 4 • -3n


i want to say its d

Answer 4

d is a guess. but then substitute 2, you need to get -12, but what do you get instead ? you get -24.

Answer 5

sooo, its b
