<u>Recursive sequence
</u>
In a recursive sequence formula, each term  is computed as a function of one or more previous terms. In the formula
 is computed as a function of one or more previous terms. In the formula

n is the number of the term we want to calculate. If n=8, then the formula becomes

We can see  is the previous term. It means we need
 is the previous term. It means we need  to be able to compute
 to be able to compute  . But we also need
. But we also need  to compute
 to compute  and so on until some known data is reached. The question provides five terms,
 and so on until some known data is reached. The question provides five terms,
