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.

= 140 in²
Answer:
Step-by-step explanation:
x = 61⁰
Reason: x + 29⁰ = 90⁰ ( right angles i.e the angles are perpendicular to one another)
x = 90⁰ - 29⁰
x = 61⁰
