Simple sequences

It is important not to be confused by the notation. In a sequence it is most common to use a subscripted number to denote the term of the sequence.

So for example, a₁ is the first term and a₁₀₀ is the 100th. Do not confuse these with powers.

This notation is taken further, as you could have variable subscripts, such as a_n+1 which means the (n+1)th term.

So a₅² means the 5th term in the sequence squared.
