The sum of three consecutive odd numbers is 69. what is the third number in this sequence?

let the first odd number = x

the sum of three consecutive odd numbers is 69

(x) + (x + 2) + (x + 4) = 69

Simplify. Combine like terms

3x + 6 = 69

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 6 from both sides

3x + 6 (-6) = 69 (-6)

3x = 63

Next, divide 3 from both sides to isolate the x.

3x/3 = 63/3

x = 63/3

x = 21

To solve for the third number, plug in 21 back into x.

(x + 4)

21 + 4 = 25

The third number is 25

hope this helps

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

10 you would take 50/ .2
