This can be written as:

2 13 (2+11) 26 (13+13) 41 (26+15)

58 (41+17) 77 (58+17) 98 (77+21) 121 (98+23) 146 (121+25)

Odd numbers are added to obtain the next term, as explained above.

The sequence up to 10 terms would be:

2, 13, 26, 41, 58, 77, 98, 121, 146

2,13,26,41,58,77,98,etc.

The difference between every two consecutive numbers is greater by 2 than between the two previous consecutive numbers, starting with it being 11 between the first two numbers.
