3.3 Chapter summary (EMA32)

Presentation: 2F85

  • The general term is expressed as the \(n^{\text{th}}\) term and is written as \({T}_{n}\).

  • We define the common difference \(d\) of a sequence as the difference between any two successive terms, where \(d=T_{n}-T(n-1)\)

  • We can work out a general formula for each number pattern and use it to determine any term in the pattern.
