Population Growth

For a living organism to survive, it has to reproduce and grow its population. We can record the population of an animal species at regular intervals, and this would result in a number sequence. We saw various types of number sequences in Meeting 2.

Fibonacci Sequence

Fibonacci (born Leonardo Bonacci), an Italian mathematcian from Pisa, is acclaimed for popularizing to the Western World the Arabic number system (1, 2, 3, 4, …) that we use today. In his book, Liber Abaci (Book of Calculation), he investigated the breeding patterns of rabbits and described the famous number sequence that bears his name.

Pairs of Rabbits: 1, then 1, then 2, then 3, etc. (Source: mathigon.org.)

Question 1: The first six numbers of the Fibonacci sequence are: 1, 1, 2, 3, 5, 8.
Take turns within your team to give the next 10 numbers in the sequence.

Use this activity’s Google Sheet to record the answers.

Points Assignment: For each number obtained correctly, the team earns 1 point. (For Question 1, maximum is 10 points).
