A(n)=A(n-1)+15 ; A(1)=23

Work Step by Step

The formula for a recursive equation is A(n)=A(1-n)+c (c is the common difference) We can find c by subtracting the first and second terms from each other. c=38-23 c=15 This gives us the equation A(n)=A(n-1)+15 ; A(1)=23 And since we know the first term in the sequence, we have to list in next to the formula.
