Question

How do I solve question 13 and 14?

Answer 1

13. 13 or 17 (not sure about this, sorry)

14. 28

Explanation:

13.

`a_(n) = \{a_(0), a_(1), a_(2), a_(3), a_(4), ... \} \\`

if counting the sequence from
`a_(0)` then
`a_(4)` is 17, but if

`a_(n) = \{a_(1), a_(2), a_(3), a_(4), a_(5), ... \} \\`

counting from
`a_(1)`, then
`a_(4)` is 13.

14.

`a_(10) = 1 + 3(10 - 1) = 1 + 3*9 = 28`
