Question 1195985
<font color=black size=3>
The nth term is {{{(-1)^n}}} assuming the pattern of {-1, 1, -1, 1, ...} repeats like that forever.


n = 1, {{{(-1)^n = (-1)^1 = -1}}}
n = 2, {{{(-1)^n = (-1)^2 = (-1)*(-1) = 1}}}
n = 3, {{{(-1)^n = (-1)^3 = (-1)*(-1)*(-1) = -1}}}
n = 4, {{{(-1)^n = (-1)^4 = (-1)*(-1)*(-1)*(-1) = 1}}}
And so on.
