    Numbers that have a prime number as the previous and successive number.

    List of prime numbers up to 200:

    2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199

    4 (coz 3 and 5 are prime)
    6 (5 and 7 are prime)
    12 (11 and 13 are prime)
    so on..

    The next 3 numbers will be 138, 150 and 180.
