What is the sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 express your answer as an improper fraction.

Sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is

Step-by-step explanation:

We need to find sum of the first five terms of the geometric sequence in which a1=5 and r=1/5

The formula used to find sum of the geometric sequence is:

Where a is the first term, r is the common ratio and n is the number of terms

Now finding sum of the first five terms of the geometric sequence

We have a=5, r=1/5 and n=5

Putting values in the formula:

So, sum of the first five terms of the geometric sequence in which a1=5 and r=1/5 is

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
