Correct Answer: 38

Solution : The difference between the first and second rows is the same as that of the difference between the second and third rows.

In the first row; 92 – 70 = 22→70 – 48 = 22
In the second row; 64 – 53 = 11→53 – 42 = 11
Similarly, in the third row; 52 – 45 = 7→45 – 7 = 38

So, the missing number is 38. Hence, the third option is correct.
