Correct Answer: C
Explanation:
Here if we look closely we can see that 3 is near to 4 which is 22
That is 3 = 4 -1 = 22 - 1
Also 15 is near to 16 which is 42
That is 15 = 16-1 = 42 - 1
And 35 = 36-1 = 62 - 1
99 = 100 - 1 = 102 - 1
143 = 144-1 = 122 - 1
So it is squares of even numbers i.e. 2, 4, 6, etc. so next should be 8 and then 10, 12.
So missing term is 82 - 1 = 64 - 1 = 63
