What number is represented by point 𝐴 on this number line?

We need to find out which number is represented here at point 𝐴. The number before point 𝐴 is also missing in the number sequence. The first thing we need to do is establish what each number or interval represents on the number line or what is each jump or skip on the number line represent.

In other words, we have to find the difference between 42 and 48. 48 minus 42 is the same as saying find the difference. And we could set it up this way. 48 minus 42 is six. So the difference is six. So the rule is we have to add six each time as we count along the number line or each interval is worth six.

To find the next number in the sequence, we need to add six to 48. If you’re not sure, you could count forward six from 48 in your head. We just start at 48 and count on six: 48, 49, 50, 51, 52, 53, 54. And to find point 𝐴, we need to count on six from 54: 55, 56, 57, 58, 59, 60. The number represented at point 𝐴 is 60.
