a(n) = (-1)^n for the nth term.

A geometric series with the first term, a = -1, and common ratio, r = -1 Tn = ar^(n - 1) Tn = -1(-1)^(n - 1) .....= (-1)^(n - 1 + 1) .....= (-1)^n Hence the nth term is (-1)^n

Ans. T(n)=(-1)^n, where n= a natural number.

Odd terms are -1, even terms are +1. So the expression is (-1)^n

nth term =-1 when n is odd and =1 when n is even

t[1] = -1 t[2] = 1 t[3] = -1 t[4] = 1 .... t[n] = (-1)^n
