Math Problem Statement
Find three consecutive integers, such that the sum of the 1st and the 3rd is 15 greater than the 2nd. Select one: 12, 13, 14 7, 8, 9 14, 15, 16 9, 10, 11
Solution
Let's define the three consecutive integers as:
- (the first integer),
- (the second integer),
- (the third integer).
According to the problem, the sum of the first and the third integer is 15 greater than the second integer. This can be written as:
Simplifying the equation:
Subtract from both sides:
Now, subtract 2 from both sides:
So the three consecutive integers are , , and .
Answer: 14, 15, 16
Would you like more details on how I solved this? Here are some related questions:
- How would you solve for consecutive integers if the sum of the first and the third was something other than 15?
- How can you generalize the process for any problem involving consecutive integers?
- What is the formula to represent three consecutive integers algebraically?
- How would the solution change if we were asked for four consecutive integers?
- Can this method be applied to solve inequalities involving consecutive numbers?
Tip: Always translate word problems into algebraic expressions first. It makes the problem much clearer and easier to solve!
