How was Series looking?
Let's take a look at the series once again.
4, 6, 12, 18, 30, 42, 60, 72, 102, 108,_,_,_
If we carefully observe the series, we can find that every Number is in between 2 PRIME numbers.
4 is in between 3 and 5.
6 is in between 5 and 7.
12 is in between 11 and 13.
So on........
108 is in between 107 and 109.
Hence next numbers should be 138, 150 and 180!
