Answer:
Arithmetic sequence
Step-by-step explanation:
-We notice that the difference between the number of favors already given out between any two consecutive number of party guests has an additive increment.
-This increment is called the Common Difference and has a value of 3.
-The number of tickets available is 50.
Hence, the number of tickets already given out can be calculated using the formula:
Hence, this is an Arithmetic Sequence.
