4 - Logic


Sequences of numbers

A sequence of numbers is a list of numbers that follow each other with a certain logic. For example :

In the sequence 0 - 2 - 4 - 6 - 8 - ... you add 2 at each step.
In the sequence 1 - 3 - 9 - 27 - 81 - ... you multiply by 3 at each step.
In the sequence 5 - 9 - 17 - 33 - ... you multiply by 2 and you subtract 1 at each step.

It is up to you to find out the logic of the sequence to discover the next numbers!

Sequences of numbers and shapes

You can also create logical suites with shapes and colors... Examples :

sequence sequence sequence sequence
In this sequence, the next shape is a blue circle with 5 red points inside.



sequence sequence sequence sequence
In this sequence, more difficult, the next shape is a green horizontal rectangle with 3 blue lines inside.
