What to Focus On
- An AP has a fixed common difference.
- The first term is denoted by a.
- The common difference is denoted by d.
- Check the difference between every pair of consecutive terms.
- A constant difference means AP.
- Changing differences mean not AP.
- Common difference is the same for every pair of consecutive terms in an AP.
- It is found by subtracting the previous term from the next term.
- A negative common difference means the sequence decreases.
Common Mistakes to Avoid
Any pattern that increases in a regular-looking way is an AP.
Prime numbers form an AP because they appear in a neat order.
The common difference is found by dividing terms, not subtracting them.
