5 7 (37) 8 4(20) 10 6(34) 6 4(?) Find missing number
Answers
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.

Answer:
(?)= (26)
Step-by-step explanation:
HELLO DEAR,
Given : 57(37), 84(20) , 106 (34), 64(?).
It is logical base question.
After making some logic you find ,
( ) = (A^2 + B^2)/ lA-Bl. .................i)
where A= (5,8,10,6)
B=( 7,4,6,4).
Now ,(1). (37) = (5^2 + 7^2)/ l5-7l
= (25+49)/ l-2l
= 74/2
(37) = 37.
(2). (20) = (8^2+4^2)/l8-4l
= (64+16)/4
= 80/4
(20)=20
(3). (34) = (10^2+6^2)/l10-6l
= (100+36)/ l4l
=136/4
(34) = 34
(4). (?) = (6^2 + 4^2)/ l6-4l
= (36+16)/2
= 52/2
(?) = 26. Answer.
I HOPE IT HELP YOU DEAR,
THANKS.
