Answer:
Option d is correct.
Step-by-step explanation:
We have given a formula [tex]a_n=3n+5[/tex]
We will put different values of n so, as to get [tex]a_n[/tex]
from the given formula
When n =1 we get
[tex]a_1=3(1)+5=8[/tex]
When n=2 we get
[tex]a_2=3(2)+5=11[/tex]
When n=3 we get
[tex]a_3=3(3)+5=14[/tex]
We can see that next term is 3 more than the previous term
Hence, [tex]a_1=8;a_n=a_{n-1}+3[/tex]
Therefore, Option d is correct.
Answer:
D. a1=8;an=an-1+3
