Answer:

946

Step-by-step explanation:

we know that

The formula to find the sum is equal to

S=(a1+an)n/2

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

n=11

a1=(98-2(1))=96

an=(98-2(11))=76

substitute the values in the formula

S=(96+76)(11/2)=946
