    The next numbers should be 138 , 150 , 180

    The series is a list of a number between two prime numbers.
    1. 138 (137 and 139 are prime)
    2. 150 (149 and 151 are prime)
    3. 180 (179 and 181 are prime)

    @#-Link-Snipped-# Keep updating this series with more of next-in-series puzzles.
