Step-by-step explanation:
The nth term for the geometric sequence is given by:
where,
is the first term
r is the common ratio
n is the number of terms.
As per the statement:
For the geometric sequence of and r=2
We have to find
for n = 5;
Substitute the given values we have;
⇒
Therefore, the value of is, 32
The correct answer is the first option.
If you want to use elimination, you can sum the two equations for example, so that the x's simplify:
Plug this value for y in one of the equations to derive the value of x:
So, the solution is
