Tju [1.3M]3 years ago

Answer:

882

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 18 and d = 30 - 18 = 12, thus

a_{73} = 18 + (72 × 12) = 18 + 864 = 882

vlabodo [156]

Answer:

[4, positive infinity)

Step-by-step explanation:

since there is a closed circle on 4, we include 4 in the continuous interval, and we assume that the arrow represents continuity after the graph ends, so the interval of continuity is from 4 to positive infinity.
