Answer 2

A)323

323 is the missing number.

11:143:17: 323

Step-by-step explanation:

Given:  

11:143:17:?

To find:

The missing number.

Solution:

• This series is a numerical analogy in which the numbers are arranged orderly and make a sequence.
• The pattern is (x₁,x₂,x₃,x₄) are the numbers in the series thus x₁, (x₁×13)⇒x₂, x₃, (x₃×19)⇒x₄.
• The pattern of this series is the prime numbers (11,13,17,19)
• The analogy is that we need to find the relation between the two numbers.
• In this number analogy we have to find it for 11:143 and 17:?

         x₁=11

The first number 11 is multiplied by 13 the next prime number 11. Thus we get 143, the second number.

11⇒143

          ⇒(11×13)

         x₂ ⇒143

The third number 17 is the next prime number to 13.

          x₃=17

17⇒?

         ⇒(17×19)

         x₄⇒323

The third number 17 is multiplied by 19 which is the next prime number to 17. Thus we get 323, the fourth number.

Hence,

The next number is 323.  

11:143:17: 323
