Watch the video to see how to sum the sequence. Can you adapt the method to sum other sequences?
Explore what happens when you draw graphs of quadratic equations with coefficients based on a geometric sequence.
In this investigation, we look at Pascal's Triangle in a slightly different way - rotated and with the top line of ones taken off.
If you continue the pattern, can you predict what each of the following areas will be? Try to explain your prediction.
Cellular is an animation that helps you make geometric sequences composed of square cells.
