7.4 Growing patterns

1. Lindiwe is making this growing pattern of pictures with
squares:

Picture 1 Picture 2 Picture 3 Picture 4 Picture 5

Lindiwe plans to continue the pattern.

(a) Describe Picture 6 and Picture 7 in words.
Now draw Picture 6 and Picture 7.
How many squares are there in Picture 6 and how many in
Picture 7?

(b) Describe Picture 60 and Picture 70 in words. Do not draw
them! Imagine them; “see” them in your head!
Calculate the number of squares in Picture 60 and in
Picture 70.
