Find the nth term of this sequence, 3, 6, 9, 12

Step-by-step explanation:

Find common difference from subtracting any term in the sequence with the previous term.

Apply nth term formula.

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)
