What is the sum of an 8-term geometric series if the first term is 12 and the last term is -3,359,232?
olga nikolaevna [1]
We must find the common ratio first...

Since a(n)=ar^(n-1)

-3359232=12r^7

-279936=r^7

-279936^(1/7)=r

-6=r

So our geometric sequence is:

a(n)=12(-6)^(n-1)

And the sum of a geometric sequence is:

s(n)=a(1-r^n)/(1-r), since a=12, r=-6, and n=8 we have:

s(8)=12(1-(-6)^8)/(1--6)

s(8)=12(1-(-6)^8)/7

s(8)= -2,879,340

A student is raising money for cancer research. A local business agrees to donate an additional 25% of what the student raises,
Blababa [14]
First, you find what 25% of $450.To do that, make 25% into a decimal, which is 0.25.Then you multiply 450 times 0.25 which is 112.5

Second, you find what 5% of 450. 5% as a decimal is 0.05. Then you multiply 450 times 0.05 which is 22.5

Third, you add 450+112.5+22.5 which is 585.

There you go. :) Hope that helped!
