5. Evaluate the series 50 + 10 + 2 + . . . 62 The series diverges; it does not have a sum. 62.5
1 answer:
Answer:
62.5
Step-by-step explanation:
By dividing 50 by 10 and 10 by 2 we can find that <em>r</em>, or the common ratio is 1/5, meaning that this series converges, so it is solvable. The formula for a convergent series is . By plugging in 1/5 for <em>r</em> and 50 for
we can find that the sum of this infinite series is 62.5

When you write a function in the form , y is the dependent variable, and x is the independent variable.
So, if b is the independent variable, it means that we have to solve the expression for r.
To do so, we perform the following steps: start with
Add 12 to both sides
Divide both sides by 4:
So, we wrote the expression in the form , which means that r is the dependent variable and b is the independent variable, as requested.
