Answer:
Option (2)
Step-by-step explanation:
If the first term of an arithmetic sequence is 'a' and common difference as 'd',
Explicit formula representing the nth term of the sequence is given by,
[tex]a_n=a+(n-1)d[/tex]
Here, n = number of term
If first term 'a' = 19 and common difference 'd' = 4
Explicit formula for the sequence will be,
[tex]a_n=19+(n-1)4[/tex]
Therefore, Option (2) will be the correct option.
