I am NOT math person. I'm a musician who needs some math help.
Given the following:
A1 = An / (r)^(n-1)
I know "An" and "r" and "n"; I want to find "A1" but only for a specific range of terms in the sequence.
Example:
A1 = 1000 / (2)^(n-1) where "n" represents every term from the 35th through the 45th term in the sequence.
How might that range of terms be illustrated in the equation?
Many thanks in advance.
