There exists a pattern of subtraction.
Step-by-step explanation:
At every step, the difference of the two numbers results in a sequence of decreasing odd numbers, beginning with 15,
63 - 48 = 15
48 - 35 = 13
35 - 24 = 11
24 - 15 = 9
So to find the next number in the sequence, let us assume it as x, so the equation would be,
15 - x = 7
15 - 7 = x
8 = x
Hence, the number would be 8.
