Question

5;7; 37 8;4; 20 6;4;? 6;10; 34

Answer 1

Given data :

Sets are

5 7 (37)   ;   8 4 (20)   ;   10 6 (34)

To find :  

The missing number in 6 4 (?)  

Solution:

Logic applied behind :

Let A, B, C are the three numbers in the given set respectively.

Then, apply C = ( A² - B²) / | A - B |

5 7 (37), Here C = 37 :

A = 5, B = 7

Then, ( 5² + 7² ) / | 5 - 7 |

       = (25 + 49) / |-2|

       = 74/2

       = 37         [=C]

8 4 (20), Here C = 20 :

A = 8, B = 4

Then, ( 8² + 4² ) / | 8 - 4 |

       = (64 + 16) / |4|

       = 80/4

       = 20         [=C]

10 6 (34), Here C = 34 :

A = 10, B = 6

Then, ( 10² + 6² ) / | 10 - 6 |

       = (100 + 36) / |4|

       = 136/4

       = 34         [=C]

6 4 (?), Here C = ? :

A = 6, B = 4

So, C = ( 6² + 4² ) / | 6 - 4 |

        = (36 + 16) / |2|

        = 52/2

        = 26         [=C]

So, 26 is the answer.
