563, 647, 479, 815, ?

The answer is 143.

The sequence is a simple alternating addition and subtraction of 182. Starting with 563, 182 is added to get 745. Then 182 is subtracted to get 563. This pattern repeats, with 182 being added and subtracted alternately.

Option A, 672, is incorrect because it is not the next number in the sequence. Option B, 386, is incorrect because it is not the next number in the sequence. Option C, 279, is incorrect because it is not the next number in the sequence. Option D, 143, is the correct answer because it is the next number in the sequence.
