  2. Yes . 252.

    2, 12 , 36, 80, 150,
    (12-2=10) (36-12=24) (80-36=44) (150-80=70)

    Now 24-10=14
    44-24 = 20
    70-44 = 26
    there is a incraese of 6 everytime and that has been added to teh differnce which gives that next differnece would be of (26+6 = 32)

    Now 32 will be added to 70 which is 102 .. adding 102+150 = 252
