Question

What is the next number in the sequence -
1, 7, 10, 13, 19, 23, 28, 31, 32, 44, 49, 68, 70, 79, 82, 86, 91, 94, 97, 100, 103, 109, 129, 130, ?

Answer 1

18 + 8^2 = 18+64 = 82
82 + 2^2 = 82+4 = 86
86 + 6^2 = 86+36 = 122
122 + 22^2 = 122+484 = 606
606 + 6^2 = 606+36 = 642
Similarly
642 + 42^2 = 2406
