The Nth Term
Finding the Nth Term:
- Sometimes, reather than finsing the next number in a linear sequence, you want to find the 41st number
- or the 110th number
- Writing 41 out or 110 numbers takes a long time
- So you can use a general rule to find them.
- to find the term in a any sequence you use the nth term rule
- this is how you do it.
- You find the difference between the numbers in the sequence
- +3 +5 +7 +9
- If the differences are all different you find the difference between the differences
- +3 +5 +7 +9
