On a Volvo V70 XC Are the cylinders numbered one through five or do they go by the firing sequence?

On the Volvo V70 XC, which features a five-cylinder engine, the cylinders are numbered sequentially from one to five, starting from the front of the engine. The firing order for the engine is typically 1-2-4-5-3. This means that while the cylinders are numbered one through five, the firing sequence is specific and should be followed for proper engine function.
