-1 = (x-1)/3
(multiply both sides by 3)
-3 = x-1
(add 1 on both sides)
x=-2
Answer:
12
Step-by-step explanation:
The given geometric series is
We want to determine the first term of this geometric series.
Recall that the explicit formula is
To find the first term, we put n=1 to get:
This gives us:
Therefore the first term is 12
