Yaa i need ans this question........

Answer 1

because the question is 5 where the two place after is 7 next 4 place is 11 so the next 4 places is 15 so I think 15 is the answer to this question

Answer 2

Let the coefficient be x.
first no. = 5x
2nd no. = 7x
Now,
(5x-9)/(7x-9)= 7/11
By solving it
x= 6
No. will be 30 and 42.
difference will be 12.
