Correct Answer: (D)
143
Explanation: The pattern is + 84, - 168, + 336,.....i.e. + 84, - (84 x 2), + (84 x 2^2), .....
So, missing term = 815 - (84 x 2^3) = 815 - 672 = 143.

The pattern is + 84, - 168, + 336,.....i.e. + 84, - (84 x 2), + (84 x 2^2), .....
So, missing term = 815 - (84 x 2^3) = 815 - 672 = 143.
So, missing term = 815 - (84 x 2^3) = 815 - 672 = 143.
