Solution & Step-by-step Explanation
The relationship between the first pair of numbers is given by the pattern:
n:n×(n+1)
For the first pair:
11:11×(11+1)=11×12=132
Following the same logic for 12:
12:12×(12+1)=12×13=156
Therefore, the missing number is 156.
n:n×(n+1)
For the first pair:
11:11×(11+1)=11×12=132
Following the same logic for 12:
12:12×(12+1)=12×13=156
Therefore, the missing number is 156.
