Value table/Finite/Index set/Evaluation/Exercise

We consider the value table

${}i$	${}1$	${}2$	${}3$	${}4$	${}5$	${}6$	${}7$	${}8$
${}a_{i}$	${}2$	${}5$	${}4$	${}-1$	${}3$	${}5$	${}-2$	${}2$

1. Compute ${}a_{2}+a_{5}$.
2. Compute ${}\sum _{k=3}^{6}a_{k}$.
3. Compute ${}\prod _{i=0}^{3}a_{2i+1}$.
4. Compute ${}\sum _{i=4}^{5}a_{i}^{2}$.
