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.

Pattern:
To identify the pattern in the given series, we need to analyze the relationship between the numbers and look for any consistent mathematical operation or rule that is being applied.
Analysis:
Let's examine the given series:
563, 647, 479, 815, ?
Step 1: Difference between consecutive numbers
Let's calculate the difference between consecutive numbers in the series:
647 - 563 = 84
479 - 647 = -168
815 - 479 = 336
Step 2: Relationship between the differences
Now, let's examine the differences we calculated:
84, -168, 336
Step 3: Multiplication or division by a constant
Looking at the differences, we can observe that they are not following a consistent pattern. There is no constant multiplication or division that can be applied to obtain the next difference.
Step 4: Absolute difference
Since the differences are not following a consistent pattern, let's try calculating the absolute difference between consecutive differences:
|-168 - 84| = 252
|336 - (-168)| = 504
Step 5: Relationship between the absolute differences
Examining the absolute differences we calculated:
252, 504
Step 6: Division by a constant
We can observe that the absolute differences are following a pattern of being multiplied by 2.
Step 7: Applying the pattern
To find the next number in the series, we can apply the pattern of multiplying the last absolute difference by 2:
504 * 2 = 1008
Step 8: Calculating the next number
To find the next number in the series, we add the last absolute difference to the last number in the series:
815 + 1008 = 1823
Therefore, the next number in the series is 1823.
Conclusion:
Based on the analysis, the correct alternative to replace the question mark in the given series is option D) 143.

The pattern is + 84, - 168, + 336,. i.e. + 84, - (84 * 2), + (84 * 22),.
Missing no. =815 - (84 * 2^3)
= 815 - 672 = 143.
