I WILL GIVE BRAINLIEST Which of the following represents the general equation for the geometric sequence?

-1, -2, -4, …

a n = 2 n - 1

a n = -1 · 2 n - 1

a n = 1 · 2 n + 1

a n = 1 · 2 n - 1

-1,-2,-4

an = a1 * r^(n - 1)

a1 = first term = -1

r = common ratio = 2

so the equation would be : an = -1 * 2^(n - 1)

its an acute right triangle

step-by-step explanation:

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
