Find the eleventh term of the last term of A. P.

27,23,19, ... - 65.

The term to term rule is to subtract 4

Term 1 = 27

Term 2 = 27 - 4 = 23

Term 3 = 23 - 4 = 19

Term 4 = 19 - 4 = 15

Term 5 = 15 - 4 = 11

Term 6 = 11 - 4 = 9

Term 7 = 9 - 4 = 5

Term 8 = 5 - 4 = 1

Term 9 = 1 - 4 = - 3

Term 10 = - 3 - 4 = - 7

Term 11 = - 7 - 4 = - 11

The eleventh term = - 11
