Non-Linear Sequences Revision Videos

Non-linear sequences include quadratic sequences as well as geometric progressions and Fibonacci type sequences. They are all detailed in the videos below.

Nth term of a quadratic sequence - Proof

Mr Hegarty shows us an algebraic proof of how to find the nth term of a quadratic sequence. This proof isn't required knowledge but it is certainly very useful and underpins you understanding of the subject.

Fibonacci type sequences

Two examples of Fibonacci type sequences, one with algebra, in this video. Thanks jayates.

Geometric progression

From his question of the week series, Mr Barton looks into some geometric sequences.
