How to find three consecutive odd numbers with a sum of 63 - Math Help - Online Tutor

The video tutorial explains how to find three consecutive odd numbers whose sum is 63. It begins by introducing the concept of consecutive numbers and focuses on odd numbers. The tutorial then uses algebra to represent these numbers with variables, leading to an equation. The instructor demonstrates solving the equation step-by-step, resulting in the numbers 19, 21, and 23. The video concludes by summarizing the solution process.

What is the sum of the example consecutive odd numbers 5, 7, and 9?

• 63

• 15

• 27

• 21

If the first odd number is represented by X, how would you express the second consecutive odd number?

• X + 2

• X + 1

• X + 4

• X + 3

What equation represents the sum of three consecutive odd numbers starting with X?

• X + X + 3 + X + 6 = 63

• X + X + 4 + X + 8 = 63

• X + X + 2 + X + 4 = 63

• X + X + 1 + X + 2 = 63

What is the first step in solving the equation 3X + 6 = 63?

• Add 6 to both sides

• Subtract 6 from both sides

• Divide both sides by 3

• Multiply both sides by 3

What are the three consecutive odd numbers that sum up to 63?

• 21, 23, 25

• 17, 19, 21

• 23, 25, 27

• 19, 21, 23
