Hello,

This figure shows the number of segments used to form longer and longer rows of squares.

It shows that 1 square has 4 segments

2 squars has 7 segments and 3 squares has 10 segments.

The question is how many segments will be in a row with 100 squares?

Thought maybe a proportion, but I'm not sure what to do.

If you make a table its simple

X|Y

1|4 (1*3+1=4)

2|7 (2*3+1=7)

3|10 (3*3+1=10)

100|? (100*3+1=301

SO the answer is there will be 301 segments.
