E(10k+16), k from 3 to 9
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

Take the first term (substitute 3 for k and then do the arithmetic) and add it to the last term (substitute 9 for k and then do the arithmetic). Multiply the result by the number of terms (count from 3 to 9 inclusive). Divide the result by 2.
