#### Answer:

If ${a}_{\textcolor{red}{n}} = 3 \textcolor{red}{n} - 5$
then
${a}_{\textcolor{red}{10}} = 25$

#### Explanation:

I'm not certain that I have interpreted the question in the way it was intended; however, if I have:
${a}_{\textcolor{red}{10}} = 3 \left(\textcolor{red}{10}\right) - 5 = 30 - 5 = 25$
