First, let's find the pattern in the given number series.
Look at the differences between consecutive numbers: 21 - 18 = 3, 27 - 21 = 6, 39 - 27 = 12. Do you see a pattern?
The difference is increasing by a factor of 2 each time (3 × 2 = 6, 6 × 2 = 12).
Now, let's find the next difference: if we multiply 12 by 2, we get 24.
So, the next number in the series should be 39 + 24 = 63.
