#### Answer

$0,2.5, 5,7.5, 10,12.5, 15,17.5$

#### Work Step by Step

The general formula for the sum of the nth term of an arithmetic series is given by $S_n= \dfrac{n}{2}(a_1+a_n)$
We know that $a_n=a_1+(n-1)d$
Thus, $S_n= \dfrac{n}{2}(2a_1+(n-1)d)$
$70= \dfrac{8}{2}(2(0)+(8-1)d)$
This gives: $d=2.5$
Thus, we have the arithmetic series is: $0,2.5, 5,7.5, 10,12.5, 15,17.5$
