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:
![a_n=-dn+S_n\\\\n= n^{th} \ guest\\d=common \ difference\\S_n=Total \ tickets \ available\\\\\therefore a_n=-3n+50](https://tex.z-dn.net/?f=a_n%3D-dn%2BS_n%5C%5C%5C%5Cn%3D%20n%5E%7Bth%7D%20%5C%20guest%5C%5Cd%3Dcommon%20%5C%20difference%5C%5CS_n%3DTotal%20%5C%20tickets%20%5C%20available%5C%5C%5C%5C%5Ctherefore%20a_n%3D-3n%2B50)
Hence, this is an Arithmetic Sequence.
