Math Problem Statement
Solution
The image contains a mathematical example from the context of inductive reasoning:
Example 3:
- Pick a number.
- Multiply the number by 4.
- Add 8 to the product.
- Divide the sum by 2.
- Subtract 5.
After completing this procedure for several numbers, use inductive reasoning to make a conjecture about the relationship between the size of the resulting number and the size of the original number.
Solution Outline:
Let's define the original number as .
Following the steps:
- Multiply by 4:
- Add 8:
- Divide by 2:
- Subtract 5:
So, after performing the operations, the final result is .
Conjecture:
The size of the resulting number is related to the original number in a linear fashion: it is double the size of the original number minus 1.
Would you like further explanation or examples? Here are five related questions for further exploration:
- What happens if the original number is negative or zero?
- How does this pattern compare to other linear functions?
- Can we reverse the process to find the original number given the result?
- What changes if we modify the constants in the process?
- How can we visualize this relationship on a graph?
Tip: Inductive reasoning involves identifying patterns based on examples, which is different from deductive reasoning that starts with general rules.
