The first term and last term in a sequence are exactly that: the starting and ending points of the sequence.
According to the provided reference, the first term is the starting point of a sequence where the sequence begins. Conversely, the last term is the ending point, or the number where the sequence concludes.
For example, consider the sequence: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19.
- The first term is 1.
- The last term is 19.
In essence, they define the boundaries of a particular sequence, marking where the set of numbers begins and ends. They play a crucial role when analyzing a sequence.
| Term | Description | Example in Sequence 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 |
|---|---|---|
| First Term | The starting number of the sequence. | 1 |
| Last Term | The ending number of the sequence. | 19 |
