a_(n)=(n(n-2))/(2)

Find the term indicated in each case: (i) a_(n)=(n^(2))/(2^(n)):a_(7) (ii) a_(n)=(n(n-2))/(n-3),a_(20) (iii) a_(n)=[(1+(-1)^(n))/2 3^(n)],a_(7)

If a_(n) = (n^(2))/(2^(n)) , then find a_(7) .

Find the next five terms of each of the following sequences given by: a_(1)=1,a_(n)=a_(n-1)+2,n>=2a_(1)=a_(2)=2,a_(n)=a_(n-1)-3,n>2a_(1)=-1,a_(n)=(a_(n-1))/(n),n>=2a_(1)=4,a_(n)=4a_(n-1)+3,n>1

A sequence of numbers A_(n)n=1,2,3... is defined as follows: A_(1)=(1)/(2) and for each n>=2,A_(n)=((2n-3)/(2n))A_(n-1), then prove that sum_(k=1)^(n)A_(k) =1
