There is a certain relationship between the pair of numbers on the either side of :: Identify the relationship between the given pair and find the missing number. 14 : 39 :: ? : 63
Understand the Problem
The question is asking to identify the relationship between the numbers in the sequence '14 : 39 :: ? : 63' and to find the missing number that completes this relationship.
Answer
The missing number is $38$.
Answer for screen readers
The missing number is $38$.
Steps to Solve
-
Identify the relationship between the numbers We have a pair of numbers: 14 and 39. To find the relationship, we can examine how 14 is transformed into 39.
-
Determine the difference Calculate the difference: $$ 39 - 14 = 25 $$ This shows that 14 is increased by 25 to become 39.
-
Apply the same relationship Next, we need to apply this relationship to the second part, where the question mark represents the missing number before 63. So, we can express this as: $$ ? + 25 = 63 $$
-
Solve for the missing number To find the missing number, rearrange the equation: $$ ? = 63 - 25 $$
-
Calculate the result Now, calculate the missing number: $$ ? = 38 $$
The missing number is $38$.
More Information
The relationship between the pairs shows that the second number is always obtained by adding 25 to the first number.
Tips
- Miscalculating the difference between the two numbers.
- Neglecting to apply the same addition/subtraction consistently.
