Option 1: 3 – 27
Option 2: 2 – 8
Option 3: 4 – 64
Option 4: 7 – 49
Correct Answer: 7 – 49
Solution : Let's check the options –
First option:
3 – 27 (27 is the cube of the number 3.)
Second option:
2 – 8 (8 is the cube of the number 2.)
Third option:
4 – 64 (64 is the cube of the number 4.)
Fourth option:
7 – 49 (49 is the square of the number 7.)
So, the fourth option differs from the other options as 49 is a square of 7, not a cube. Hence, the fourth option is correct.
