Question

You need 2 yards of fabric to cover 3 pillows and 6 yards to cover 9 pillows . How much fabric do you need to cover 15 pillows? Help me!

Answer 1

You need 10 yards to cover 15 pillows.

This is because the patterns are increasing by 4 and 6.

PATTERN 1: 2, 6, 10...

PATTERN 2: 3, 9, 15...

See the pattern? The next number is 10. This would be easier on a number line.

I hope this helped you! :)
