Answer:
a(n) = 3 + 3(n -1)
Step-by-step explanation:
Note that each new term is found by adding 3 to the previous term. The first term is 3 and the common difference is 3. Thus, the formula for the nth term is
a(n) = a(1)+d^(n - 1)
or, in this case,
a(n) = 3 + 3(n -1)
Answer:
Step-by-step explanation:
Find common difference from subtracting any term in the sequence with the previous term.
Apply nth term formula.
