Answer:
Hi!
Step-by-step explanation:
i would love to help you, but i don't quite understand the question.
Could you please tell me so i can better help you?
They're not congruent.
If you count the numbers between AC and BE, they're different.
AC - goes from -7 to 0, which is 7 spaces
BE - goes from -2 to 6, which is 8 spaces
Answer:
I'm going with B, but i did some research.
Step-by-step explanation:
Answer:
4374
Step-by-step explanation:
common ratio is -3
geometric sequence
an = a1 * r^(n-1)
a8 = -2*-3^(8-1)
a8 = -2*-3^7
a8 = -2 * (-2187)
a8 = 4374
