Question

The fourth term of an=(1/2)^n is

Answer 1

1/16

Explanation:

the nth term is

`a_(n) = ((1)/(2) )^(n)`

the 4th term is found by substituting n=4

`a_(4) =((1)/(2) )^(4) = (1^(4) )/(2^(4) ) = (1)/(16)`

Answer 2

`1/16`

Explanation:

The formula for the sequence
`a_n=(1)/(2)^n` is used to find the
`n`th term of the sequence.

To find the fourth term, substitute
`n=4`:

`a_4=\left((1)/(2))\right ^4,\\a_4=(1^4)/(2^4)=\boxed{(1)/(16)}`
