Find $a_{1}$ by plugging in 1 into n:
$a_{1} = 98-2(1)=96$

Find $a_{11$ by plugging in 11 into n:
$a_{11} = 98-2(11)$
$a_{1} =98-22=76$

Now to find the sum your formula is:
$S_{n} = \frac{n}{2} ( a_{1} + a_{n})$
$n = 11, a_{1} = 96 , a_{11} =76$

Now plug that into the formula
$S_{11} = \frac{11}{2} (96+76)$
$S_{11} = 5.5(172)=946$

Hope that helps
