Find d for an A.P. if (i) t_(10) =20, t_(9) = 18 (ii) t_(n) = 7, t_(n-1) = 10

Prove the following by the method of induction for all n in N : Given t_(n+1) = 5t_(n+4), t_1 = 4. P.T t_n = 5^(n -1)

If t_(n)=(1+(-2)^(n))/(n-1) , find t_(6)-t_(5)

Write the indicated terms in each of the following sequences whose nth terms are: t_(n)=(n(n^(2)+5))/(4):t_(4),t_(5)
