Question #e6c63

Answer 1

Since we know the values of n, plug in the values of n into the given formula.

Explanation:

Since the problem gives us the explicit formula, we can simply plug in the values for n:
For `a_1`, we know `n=1`, so:
`a_1=(-1)^1/(1)^2=-1`

For `a_2`, we know `n=2`, so:
`a_2=(-1)^2/(2)^2=1/4`

For `a_3`, we know `n=3`, so:
`a_3=(-1)^3/(3)^2=-1/9`

For `a_4`, we know `n=4`, so:
`a_4=(-1)^4/(4)^2=1/16`

For `a_100`, we know `n=100`, so:
`a_100=(-1)^100/(100)^2=1/10000`
