Answer: = 3n + 1 , n≥ 1
Step-by-step explanation:
The common difference of the sequence = 3 , so it is an arithmetic sequence.
The formula for the nth term of an arithmetic sequence is given as:
= a + (n-1)d
substituting the values of a and d , we have
= 4 + (n-1) X 3
= 4 + 3n - 3
= 1 + 3n
= 3n + 1 , n≥ 1
