The value of A in the number line is the in-between of 225 and 645 so it is 435.
<h3>What is a number line?</h3>
In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given the number line,
Now if we count the interval of A between 225 and 645 it is 2(same).
So A must be between 225 and 645.
So,
225 - A = A - 645
2A = 870
A = 435
Hence "The value of A in the number line is the in-between of 225 and 645 so it is 435".
