In these formulas, d is the common difference and A(1) is the first term. Looking at the given recursive formula, we can identify the common difference d and the value of the first term A1.
A(n)=A(n−1)+3;A(1)=6
We can see that 3 is the common difference and the first term is 6. Now we have enough information to form an explicit formula for this sequence.
