Question

the sum of three consecutive odd numbers is 243.what are the numbers?

Answer 1

Answer:

79, 81, and 83

Step-by-step explanation:

the sum of three consecutive odd numbers is the same as the sum of the middle one used three times .

243÷3=81, that's the middle one

81-2=79, that's the first one

81+2=83 , that's the third one

Hope this helps.

Answer 2

Answer:

{79, 81, 83}

Step-by-step explanation:

Represent these consecutive odd numbers by x, x + 2, x + 4.

Their sum is x + x + 2 + x + 4 = 243.

Combining like terms, we get:

3x + 6 = 243, or

3x = 237

Dividing both sides by 3, we get:

x = 237/3 = 79

Thus, the first number is 79, the next is 79+2, or 81, and the last is 81 + 2, or 83:  {79, 81, 83}
