Free Sequences n-th term calculator - calculate the n-th term of a sequence step-by-step Step 1: Confirm the sequence is quadratic. This is done by finding the second difference. Sequence = -3, 8, 23, 42, 65 1st difference = 11,15,19,23 2nd difference = 4,4,4,4 Step 2: If you divide the second difference by 2, you will get the value of a. 4 ÷ 2 = 2 So the first term of the nth term is 2n²
