The sum of 3 consecutive odd numbers is 183. What is the third number in this sequence?

Answer:
The third number in this sequence is 63.
Step-by-step explanation:
Let the first odd number be <em>x</em>.
Since our sequence are consecutive odd numbers, the second term must be (<em>x</em> + 2) and the third (<em>x</em> + 4). If we only add one, we will get even numbers.
Their sum is 183. Hence:
Solve for <em>x</em>. Combine like terms:
Subtract six from both sides:
And divide both sides by three. Hence:
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 <em>x</em>, we can conclude that no three consecutive integers sum to 183.

Answer:
12/x^5
Step-by-step explanation:
The fractions are multiplied in the usual way. The applicable rule of exponents is ...
(x^a)(x^b) = x^(a+b)

<u>Solution-</u>
Fuel consumption rate = 40 miles per UK gallon (As the car is manufactured in UK)
1 UK gallon = 4.5459631 lit
1 US gallon = 3.7853060 lit
As the fuel consumption rate = 40 miles per gallon
⇒ You need 1 UK gallon of fuel to go 40 miles
⇒ You need 1.2009499 US gallon of fuel to go 40 miles
Or you can say that, to go 40 miles you need 1.2009499 US gallon of fuel
⇒ To go 1 mile you will need
⇒ To go 738 miles you will need 0.0300237×738 = 22.1574906 US gallon of fuel
∴ 22.1574906 gallon of fuel is actually required.
∴ But, what she thinks will require is (As she calculated using UK gallons)
