Question

For the sequence an = 3n - 5, what is the value of a10?

Answer 1

If `a_color(red)(n) = 3color(red)(n) -5`
then
`a_(color(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_(color(red)(10)) = 3(color(red)(10)) - 5 = 30 -5 = 25`
