Hey people,
The beginning of a series is shown in a problem.
(7)/(1*1-1) - (7)/(2*2-1) + (7)/(3*3-1) - (7)/(5*5-1) + (7)/(8*8-1) - ...
I had tried to input this into a sigma sum, but I do not know how to only get it to occur on Fibonacci numbers.
This is what I have so far
((7)(-(-1)^k)) / ((k-1)(k+1))
