Question

What is the number? I know it isn't 290. Please I need help on this otherwise it's a detention and have several other assignments to do.

Answer 1

Since there are 5 spaces between each multiple of 100, you know that each tick mark between them represents a multiple of 20. The marked number is the 4th tick mark, which means it is 200 + 4(20), or 280.

Answer 2

280

Explanation:

each individual line is a +20, therefore one line before 300 would be 300-20=280
