    a1 = 9 a2 = a1 + 2 = 11 a3 = a2 + 2 = 13 a4 = a3 + 2 = 15 . . . . . . . a12 = a11 + 2 = 31 this is recursive formula..

    expicit formula is An = a1 + (n - 1) d An = 9 + ( n - 1) 2

    z^2(1 + 1/2 + 1/2^2 + 1/2^3........1/2^15) = z^2 ( 1 . ( 1 - 1/2^15) over 1 - 1/2

    z^2 ( .99) x 2 z^2 (1.99) = 2z^2..after rounding
