Question

what should be added to each of the number to make it in proportion 4,7,14,22

Answer 1

Let the 4+x , 7+x , 14+x , 22+x be in proportion

Now,( 4+x) × (22+x) =( 7 + x) × (14+x)

88 + 26 x + x² = 98 + 21 x + x²

26 x -21 x = 98 - 88

5 x = 10

x = 2 .

Therefore, 2 must be added to all numbers to make 4 , 7 , 14 , 22 in proportion.

Answer 2

Hey....


Answer :- 4+x , 7+x , 14+x , 22+x be in proportion 

Now,( 4+x) × (22+x) =( 7 + x) × (14+x) 

88 + 26 x + x² = 98 + 21 x + x² 

26 x -21 x = 98 - 88 

5 x = 10

x = 2 .
