The sum of 3 consecutive odd numbers is 69
What is the third number in this sequence?
Let's represent the first odd number as x. The second odd number will be x+2, and the third odd number will be x+4.
The sum of these three consecutive odd numbers is x + (x+2) + (x+4) = 69.
Combining like terms, we get 3x + 6 = 69.
Subtracting 6 from both sides, we have 3x = 63.
Dividing both sides by 3, we find x = 21.
Therefore, the third odd number in this sequence is 21 + 4 = 25.
