1, 4, 4^{2}, 4^{3}, 4^{4}

Level:

First five terms of four sequences are given. One of these sequences is not a geometric sequence. Choose this sequence.

\frac{1}{2}, \frac{1}{4}, \frac{1}{6}, \frac{1}{8}, \frac{1}{10}

1, - 1, 1, - 1, 1

Level:

The picture shows a part of the graph of a geometric sequence. What is the common ratio of the geometric sequence?

- \frac{1}{2}

- 2

\frac{1}{2}

{(- \frac{1}{2})}^{n}

Level:

A sequence of patterns uses grey and purple squares. Identify the false statement about the numbers of squares in the patterns.

The numbers of grey squares in patterns do not form a geometric sequence.

The numbers of purple squares in patterns form a geometric sequence with an even common ratio.

The numbers of purple squares in patterns form a geometric sequence with a positive common ratio.

The numbers of grey squares in patterns form a geometric sequence with an even common ratio.
