Sum to n terms the following series :
5 + 11 + 19 + 29 + 41 + .......
3 + 7 + 14 + 24 + 37 +......
6 + 9 + 16 + 27 + 42 + .....
5 + 7 + 13 + 31 + 85 + ....
In the first series, the differences between consecutive terms are 6, 8, 10, and 12, which form an arithmetic progression. This consistent secondary pattern identifies the sequence as the correctly structured number series among the choices. Therefore, 5 + 11 + 19 + 29 + 41 is the intended correct series.
