Let's consider the first number to be and the second number to be
. Based on the information in the problem, we can create the following equations:
Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:
Now, subtract from both equations to get:
Now that we have found , "plug" it back into an equation to find
:
Our answers are s = -4 and f = 9.
Sum is
r=common ratio
a1=first term
it looks like 2^0=1 is the first term aka a1
it goes to the 9th term (2^9)
