    Find the next two terms of the elements of the sequence 1, 8, 9, 32, 49, ...

    1 + 7 = 8

    8 + 11 = 19

    19 + 13 = 32

    32 + 17 = 49

    49 + 19 = 68

    68 + 23 = 91

    From the patterns, we can extablish the similarities. A prime number is added to the previous number.

    Thus the two numbers are: 68 and 91
