Please just give me answer checking my answers to make sure my answers ok. I don't need the steps

Answer 1

Given:

The explicit formula for a geometrc sequence is given:

`a_n=500*(0.5)^(n-1)`

To find the 6th term put n=6 here,

`\begin{gathered} a_6=500*(0.5)^(6-1) \\ =500*(0.5)^5 \\ =500*0.03125 \\ =15.625 \end{gathered}`

Hence, option B is correct.
