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.

    Oh, so you had to find a pattern...
    Thanks
