Find first term a1: We start by finding the first term a1 by plugging n=1 into the explicit formula.a1=13(1)−36=13−36=−23.
Find second term a2: Next, we find the second term a2 by plugging n=2 into the explicit formula.a2=13(2)−36=26−36=−10.
Calculate common difference d: Now, we calculate the common difference d by subtracting a1 from a2.d=a2−a1=−10−(−23)=−10+23=13.
Use recursive formula: The recursive formula for an arithmetic sequence is an=an−1+d. We substitute d=13 into this formula.an=an−1+13.
