Answer:
143
Step-by-step explanation:
The terms 5, 7, 9, 11, 13 form an arithmetic progression with n th term
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n - 1)d
where d is the common difference and [tex]a_{1}[/tex] the first term
d = 13 - 11 = 11 - 9 = 9 - 7 = 7 - 5 = 2 and [tex]a_{1}[/tex] = 5, hence
[tex]a_{70}[/tex] = 5 + (69 × 2 ) = 5 + 138 = 143
