Lesson details
Key learning points
- Visual representations of a sequence can help with identification.
- Special number sequences can produce interesting graphs.
Keywords
Triangular number - A triangular number (or triangle number) is a number that can be represented by a pattern of dots arranged into a triangle.
Common misconception
Pupils may think that given a graph is continuous, the sequence can contain all of the values represented by the line.
It is important that pupils know when it is appropriate to draw a line to graph sequences and whether values on the line have any meaning. Sequences are often given as a list of terms and without context we cannot assume the sequence is continuous.
