Answer:
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.
