In order to find the common difference of the data in the problems you have to follow those steps.

We know that 
 
the arithmetic sequence the difference  between one term and the next is a constant in called common difference.

Let
1x=1 y1=24
2x=2y 2=24.38
3x=3y 3=24.76
4x=4y 4=25.15
so
y2-y1=24.38-24=0.38
y3-y2=24.76-24=0.38
y4-y3=25.15-24=0.38

the difference of the is the result of let would be the correct answer 
so in  a simpler way to explain it subtract 24 from 24.38 and that would be the answer
