Answer:
The required equation is [tex]a_n=a_1+(n-1)d[/tex]
Step-by-step explanation:
To find : Which of the following are explicit equations for the nth term of some kind of arithmetic sequence?
Solution :
The Explicit formula which shows the nth term of a sequence in terms of n is given by,
[tex]a_n=a_1+(n-1)d[/tex]
Where, [tex]a_n[/tex] is the nth term
[tex]a_1[/tex] is the first term
n is the number of terms
d is the common difference
Therefore, The required equation is [tex]a_n=a_1+(n-1)d[/tex]
