Answer:
Step-by-step explanation:
Let the first term be , then the terms of the sequence are:
.
Since the fourth term is 108, we have
Hence the sequence becomes:
.
The explicit expression for a geometric expression is given by:
where a=4 and r=3
The required formula is:
we are given
we have to solve it by completing square method
step-1: Move 5 on right side
step-2: Break middle term
step-3: Add 6^2 both sides
step-3: Solve for x
we wil get two values
First value is
add both sides 6
Second value is
add both sides 6
so, solutions are
