Answer:
Joan's older sister weighs 90 pounds
Step-by-step explanation:
x = older sister
x - 10 = Joan
(x + (x-10))/2 = 85
2x - 10 = 170
2x = 180
x = 90
The series is a convergence series and the sum of the series is -8/3
<h3>The type of the series</h3>
The series is given as:
The above series has the following properties:
- First term; a = -4
- Common ratio, r = -1/2
Start by calculating the absolute value of the common ratio
Absolute value = |-1/2|
This gives
Absolute value = 1/2
The above value is less than 1.
It means that the series converges.
<h3>The sum of the series</h3>
This is calculated using:
So, we have:
Evaluate the sum
Evaluate the quotient
Hence, the sum of the series is -8/3
