Answer:
Step-by-step explanation:
Red = r, blue = b,
Substitute:
- 9b = b + 288
- 8b = 288
- b = 288/8
- b = 26

Step-by-step explanation:
You can only find the sum of an infinite geometric sequence if it converges.
One criterion to see if the series converges is if:
aₙ < aₙ₋₁
This means that, as n increases, the value of the terms decreases.
This means that as n tends to infinity, aₙ tends to zero.
Then we only can find the sum of those series where the terms are decreasing.
in A, B and D the terms are decreasing, then we can find the sum of those 3 series.
Now in the case of C, the terms are increasing, then we can not find the sum of that series.
The order of operations is used to order numerical expressions
