Answer:
B. 218
Step-by-step explanation:
Step 1
The first step is to write down the formula for an arithmetic sequence and state the given values. The formula for an arithmetic sequence is
[tex]a_n=a_1+(n-1)d.[/tex] We are given that [tex]a_1=5,d=3[/tex]
Step 2
Determine the term that is required. We are required to find the 72nd term of the sequence. We will use the formula to calculate this term as shown below,
[tex]a_n=a-1+(n-10d\\ a_{72}=5+(72-1)\times 3\\a_{72}=5+71\times 3\\a_{72}=218[/tex]
