What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence ,

and 3rd term of Geometric Sequence,

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

So,

So, 3rd term = 112

a × (-2)² = 112

a = 112 / 4

a = 28

Therefore, The first term is 28.

factor trees are nice.

hope i'm right lol
