Question

Make a pattern without numbers and shapes in the given boxes.

Answer 1

Any pattern which doesn't have a number or a shape in it can be formed here.

So the pattern can be formed using letters of english alphabet.
The pattern should be based on a rule.

Rule: Three continuous letters of the English alphabet are grouped together and every next term starts with the next letter to the ending letter of the previous group.

Patten can also be formed using colours.
An example is shown here.
