The sum is:
--------------------------------------------------------------------
If the sequence is infinite, the formula is:
-------------------------------------------------------------------
Step-by-step explanation:
We must calculate the radius of the geometric series
The first term of the series is:
The last term of the series is:
If the sequence is finite then the formula is:
If the sequence is infinite then by definition as the radius are then the formula for the sum of the geometric sequence is:
subtract 10 from both sides
multiply each side by 3
the "blank" is equal to twelve
