Solved Example on Conjecture
Sam proposed that '3n + 1 yields a prime number for any even number, n.' and called it a conjecture.
He explained his conjecture using the numbers 2, 4, and 6. He got 7, 13, and 19.
Is his proposition a conjecture?
Choices:
A. Yes
B. No
Correct Answer: B
Solution:
Step 1: A conjecture is a statement that is believed to be true but not yet proved or disproved.
Step 2: Sam's proposition is not a conjecture, because for n = 8, 3n + 1 gives 25, which is not a prime number.
