2. (n!)/(n-2!) n= 2,3,4... Converges or Diverges? If converges where does it converge?
3. Summation of n=0 goes to infinity of the equation 2(-1/2)^n Converges where?
Hello,Originally Posted by Nimmy
to 2.) I hope you meant . Then you can transform this term to:
and thats (n-1)*n which doesn't converge for n to infinity.
to 3. Split the summation into two sums: In 1st sum n is even and the numbers are positive, in the 2nd sum n is odd and all numbers are negative. Calculate both sums separately.
This sum must converge according to the convergence criterium of Leibniz.

Ok Let me rephrase the question just to make sure the ppl in the fourm understandOriginally Posted by ThePerfectHacker
Find the sum of the geometric series:
= 2-1+1/2-1/4...
can u explain how you got it to converge at 3/2?
