The options for this questions are missing:
A. 672
B. 386
C. 279
D. 143
The answer to this question is option D, 143.
The pattern is + 84, - 168, + 336,.....i.e. + 84, - (84 x 2), + (84 x 22), .....
So, missing term = 815 - (84 x 23) = 815 - 672 = 143.

Given series is 563 , 647 , 479 , 815 , ?
we can get next term only when we know what the patterns is used in this series .
Let's try to find patterns !
647 - 563 = 84
479 - 647 = -168 = -2 × 84
815 - 479 = 336 = 4 × 84
here we see , +84 , -2 × 84 , + 4 × 84
then definitely next term will be -8 × 84
now, Let next term of series is X
X - 815 = -8 × 84
X = 815 -672 = 143
hence, next term is 143
