Answer 11

that rule that they give you for calculating the terms from 9 to 22

when i = 9 what do you get?

Answer 12

the latex font does bad for 9s ... but they dont seem to wanna change it

Answer 13

so i do 13 plus 9? and get 22 so thats the 1st term?

Answer 14

since the rule, fucntion, equation, thing to use ... is defined there is:

10i + 3

i would use it to determine the value when i = 9 and then when i = 22

10(9) + 3 = ?

10(22) + 3 = ??

Answer 15

oh so i substitute everynumber from 9 to 22 in for i
then add them up?
