What to Focus On
- A sequence is ordered and follows a rule.
- The nth term is the general term.
- A finite sequence has a limited number of terms.
- A series is the sum of terms of a sequence.
- Sigma notation is a compact way to write sums.
- The expression and its numerical sum are not the same thing.
- In a G.P., the ratio between consecutive terms is constant.
- Every term of a G.P. must be non-zero.
- The first term is a and the common ratio is r.
Common Mistakes to Avoid
A sequence and a series mean the same thing.
The nth term is always the sum of the first n terms.
Every sequence must have a neat formula for its nth term.
Memory Tips
Sequence as ordered terms
Nth term as general term
Finite and infinite sequence
Sequence as a function
