Final answer:
To find positive integers when divided by 4 leave the remainder of 3, we can use the equation x ≡ 3 (mod 4) and list out the positive integers that satisfy this condition.
Step-by-step explanation:
In this case, we are looking for positive integers that, when divided by 4, leave a remainder of 3. To find these numbers, we can use the equation x ≡ 3 (mod 4), where x represents the positive integers we are looking for.
By listing out the positive integers and calculating their remainders when divided by 4, we can identify the numbers that satisfy the given condition.
The positive integers that meet the criteria are: 3, 7, 11, 15, 19, 23, 27, 31, 35, 39, 43, ...
