Question

Let say I am a 4 digit number, my first digit is 3,my second and third digit are two consecutive odd numbers whose product is 15 .my last digit is half of one more than my first digit and third digit minus the second digit is one less than my first digit. Write me in standard form

Answer 1

The 4-digit number described by the student's conditions is 3522.

Step-by-step explanation:

The student is described as a 4-digit number with various specified attributes.

The first digit is 3.

The second and third digits are consecutive odd numbers whose product is 15, which are 3 and 5. Since only odd numbers can be multiplied to get an odd product and the possible factors of 15 are 3 and 5, these must be the second and third digits.

The last digit is half of one more than my first digit, which means ½ (3+1) = 2.

Finally, the third digit minus the second digit should be one less than the first digit, which is true because 5 - 3 = 2, and 2 is indeed one less than 3.

Therefore, the number in standard form is 3522.
