Answer:

61

Explanation:

3x + 6 = 183

3x = 177

Answer:

The third number in this sequence is 63.

Explanation:

Let the first odd number be x.

Since our sequence are consecutive odd numbers, the second term must be (x + 2) and the third (x + 4). If we only add one, we will get even numbers.

Their sum is 183. Hence:


x+(x+2)+(x+4)=183

Solve for x. Combine like terms:


3x+6=183

Subtract six from both sides:


3x=177

And divide both sides by three. Hence:


x=59

Therefore, our sequence is 59, 61, and 63.

The third number in this sequence is 63.

Note: If we do not get an odd number or if we get a fraction for x, we can conclude that no three consecutive integers sum to 183.
