Definition Niveau 2
The sum of a given number of terms in a sequence
Consider the sequence 1, 3, 5, 7, 9, 11, 13, 15..... the sum of the first five odd numbers is 1+3+5+7+9 = 25
Consider the sequence 1, 8, 27, 64, 125, 216..... The sum of the first four cube numbers is 1+8+27+64 = 100

Definition Niveau 4
A sequence where the nth term is the sum of the first n terms of another sequence. Eg the sequence of whole numbers:
1, 2, 3, 4, 5, 6, 7 ... gives the series
1, 3, 6, 10, 15, 21, 28 ... (the triangular numbers).
1, 2, 3, 4, 5, 6, 7 ... gives the series
1, 3, 6, 10, 15, 21, 28 ... (the triangular numbers).
