In the following question, select the missing number from the given series.
9863, 7119, 4922, 3194, 1863, ?
Given series is  9863, 7119, 4922, 3194, 1863, ?
The logic here is
9863 - 7119 = 2744 = 14$$^3$$
7119 - 4922 = 2197 = 13$$^3$$
4922 - 3194 = 1728 = 12$$^3$$
3194 - 1863 = 1331 = 11$$^3$$
The difference between the numbers is the cube of consecutive numbers.
The next difference will be 10$$^3$$ = 1000
Let the missing number = a
$$\Rightarrow$$Â 1863 - a = 1000
$$\Rightarrow$$Â Â a = 863
$$\therefore\ $$The missing number in the series = 863
Hence, the correct answer is Option C
