A Fibonacci sequence is a sequence where each term is the sum of the two previous terms.

An alternating sequence is a sequence where consecutive terms change sign.

Fibonacci and alternating sequences

Maths

In the prior unit, pupils considered other types of graphs. In this unit, pupils consider different types of sequences such as Fibonacci and oscillating. Their knowledge is consolidated by linking all prior learning together.
