Question from Alice, a student: Find the 24th term of this sequence |
Hi Alice,
The sequence is arithmetic so you can use the following formulae:
| an | nth term in the sequence |
| am | mth term in the sequence |
| d | difference between consecutive terms |
| n, m | term position in sequence (1st, 2nd, 3rd, etc.) |
| a1 | first term in the sequence |
| Sn | sum of the first n terms |
Hope this helps,
Janice
