Question : Directions: Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row – 7, 343, 49
Second row – 6, 216, 36
Third row – 5, 125, ?
Option 1: 30
Option 2: 45
Option 3: 25
Option 4: 85
Correct Answer: 25
Solution :
Given:
First row – 7, 343, 49
Second row– 6, 216, 36
Third row– 5, 125, ?
In each row, the second number is the cube of the first number, and the third number is the square of the first number.
Like, first row: 7, 343, 49→(7)
3
= 343; (7)
2
= 49
And, second row: 6, 216, 36→(6)
3
= 216; (6)
2
= 36
Similarly, follow the same pattern for the third row 5, 125, ?→(5)
3
= 125; (5)
2
= 25
So, the missing number is 25. Hence, the third option is correct.
