8(89)9,11(155)12,4(34)6

Step-by-step explanation:

Given:

8(89)9,11(155)12,4(?)6

To find:

The missing number in the series

Solution:

This series is a numerical sequence in which the numbers are arranged orderly and make a sequence.

The pattern of this series is the numbers outside the brackets are added and multiplied and then the resulted multiplied number is then added with the added number we get the bracket number.

8(89)9,11(155)12,4(?)6

The number 8 is multiplied by 9 and then added with (8+9). Thus we get 89, the first sequence.

 8(89)9

        ⇒(8×9)+(8+9)

        ⇒(72)+17

        ⇒89

The number 11 is multiplied by 12 and then added with (11+12). Thus we get 89, the second sequence.

11(155)12

         ⇒(11×12)+(11+12)

         ⇒132+23

         ⇒155

The number 4 is multiplied by 6 and then added with (4+6). Thus we get 89, the third sequence.

4(?)6

The missing number in the series is

           ⇒(4×6)+(4+6)

          ⇒24+10

          ⇒34

Hence,

The missing number in the series is 34.  

8(89)9,11(155)12,4(34)6
