t_(n)=(n-1)(2-n)(3+n);t_(20)

Find the indicated terms in each of the following sequences whose nth nth terms are: t_(n)=(n(n-2))/(n+3),t_(20)

What is the 20^(t h) term of the sequence defined by a_n=(n-1)(2-n)(3+n)?

The Fibonacci sequence is defence by t_(1)=t_(2)=1,t_(n)=t_(n-1)+t_(n-2)(n>2). If t_(n+1)=kt_(n) then find the values of k for n=1,2,3 and 4.

Let the n^(th) term of a series be given by t_(n)=(n^(2)-n-2)/(n^(2)+3n),n<=3. Then product t_(3)t_(4).....t_(50) is equal to

Find the term indicated in the following case : t_(n)=4^(n)+n^(2)-n+1 ,t_(3) .

Find the terms (s) indicated in each case: (i) t_(n)=t_(n-1)+3(ngt1),t_(1)=1,t_(4) (ii) T_(n)=(T_(n-1))/(T_(n-2)),(ngt2),T_(1)=1,T_(2)=2,T_(6)

Write the next three terms of the following sequences: t_(1)=1,t_(n)=(t_(n-1))/(n),(n>=2)

If (1^2-t_1)+(2^2-t_2)+….+(n^2-t_n)=(n(n^2-1))/(3) then t_n is equal to

If (1^2-t_1)+(2^2-t_2)+….+(n^2-t_n)=(n(n^2-1))/(3) then t_n is equal to

The absolute value of the sum of first 20 terms of series, if S_(n)=(n+1)/(2) and (T_(n-1))/(T_(n))=(1)/(n^(2))-1 , where n is odd, given S_(n) and T_(n) denotes sum of first n terms and n^(th) terms of the series
