Answer:

The value of the unknown in the analogy equation 29: 72:: 79: ? is 131.

Step-by-step explanation:

Assumption,

Let the value of unknown be 'x'.

Given,

The analogy equation:

29: 72:: 79: x

To find,

The value of 'x'.

Calculation,

From observation, we can conclude that:

29 is the 10th prime number from the prime number series.

And similarly, 72 is the 20th prime number in the prime number series.

So, the difference in no. of prime numbers between two numbers is 10.

Hence, 79 is the 22nd prime number so, the 42nd (22 + 10) prime number in the prime number series is 131.

Therefore, the value of the unknown in the analogy equation 29: 72:: 79: ? is 131.
