32,52 
to get the third no add 5+2 =7 is the first digit of the 3rd no 
to get the second digit u need to find the difference between (addition of the digits of second no and addition of digits of the first no) i.e. (5+2)-(3+2)=7-5=2 
so the third no is 72 
similarly for the fourth no. 
first digit (7+4)=11 
second digit ((7+4)-(5+2))=11-7=4 
next no should be 114 
.... 
last number 135 
13+5 = 18 
The last digit is the difference between the last two answers, in this case, 18-13 = 5. 

ANSWER: 185 = 17

Answer:  The required missing number is 8.

Step-by-step explanation:  We are given to find the missing number in the following proportion :

[tex]\dfrac{32}{52}=\dfrac{?}{13}.[/tex]

Let the missing number be represented by x.

Then, according to the given information, we have

[tex]\dfrac{32}{52}=\dfrac{x}{13}\\\\\\\Rightarrow \dfrac{8}{13}=\dfrac{x}{13}\\\\\\\Rightarrow x=\dfrac{8}{13}\times13\\\\\Rightarrow x=8.[/tex]

Thus, the required missing number is 8.
