What does this all mean? ,
Patients may include, but may not be exclusively, non-Medicare Part B FFS patients. ,
To find out how many bottles he brewed on Friday, we need to look for a pattern in the numbers.
On Monday, he brewed 1 bottle.
On Tuesday, he brewed 4 bottles (3 more than Monday).
On Wednesday, he brewed 9 bottles (5 more than Tuesday).
On Thursday, he brewed 16 bottles (7 more than Wednesday).
From this pattern, we can observe that the number of bottles he brews each day increases by 2 compared to the previous day.
So, to find out how many bottles he brewed on Friday, we can continue the pattern:
On Friday, he brewed 16 + 2 = 18 bottles.
Therefore, he brewed 18 bottles on Friday.
