Calculate first term: Calculate the first term a1 using the explicit formula.a1=14(1)−23a1=14−23a1=−9
Calculate second term: Calculate the second term a2 using the explicit formula.a2=14(2)−23a2=28−23a2=5
Find common difference: Find the common difference d by subtracting a1 from a2.d=a2−a1d=5−(−9)d=5+9d=14
Write recursive formula: Write the recursive formula using the common difference d.an=an−1+dan=an−1+14
