Arithmetic progression
highAn arithmetic progression, or AP, is a sequence in which each term after the first is obtained by adding the same fixed number every time.
Always check the difference between consecutive terms before calling a sequence an AP.
Common difference
highThe common difference is the fixed number added to each term of an AP to get the next term.
Keep the order of subtraction the same as the order of the sequence: next term minus previous term.
