Use the comparison test to determine whether the series is convergent or divergent
Lunna [17]

Answer:

b) diverges

Step-by-step explanation:

Given is a series with the terms

\frac{25}{3} +\frac{125}{9} +\frac{625}{27} +...

We find that this series follows a pattern such that each term is multiplied by 5/3 to get the next term.

In other words, this is a geometric series with  I term=25/3 and common ratio=5/3

Sum of geometric series upto n terms

=\frac{a(r^n-1}{r-1} =\frac{25}{3} (\frac{(\frac{5}{3} )^n-1}{\frac{5}{3}-1 } )\\

Since r>1, we find that this series diverges to infinity

Hence answer is

B) divergent

14. Find the average of the 1000 whole numbers
steposvetlana [31]

Answer:

500.5

Step-by-step explanation:

The average of a set of numbers is the sum of the numbers divided by the number of numbers.

The sum of all whole number form 1 to n is n(n + 1)/2.

The sum of all whole numbers from 1 to 1000 is

1000(1000 + 1)/2 = 1000(1001)/2 = 500,500

The average is the sum of the numbers divided by the number of numbers.

average = 500,500/1000 = 500.5
