What are the explicit equation and domain for a geometric sequence with a first term of 4 and a second term of -12? (5 points)

an = 4(-3)n - 1; all integers where n ≥ 1

an = 4(-3)n - 1; all integers where n ≥ 0

an = 4(36)n - 1; all integers where n ≥ 1

an = 4(36)n - 1; all integers where n ≥ 0

Is it A? @jdoe0001 @ParthKohli @jinxhead20 @nelsonjedi @NeedHelpQuick546 @suckerofmath

@nelsonjedi Well is it?

It's d because it would be a rational number if you plugged in 0 for n, so it has to be greater than or equal to 1.
