WebThis 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 … WebWith the recursive equation for a sequence, you must know the value of the prior term to create the next term. So, you follow a repetitive sequence of steps to get to the value you want. For example, to find the 4th term of a sequence using a recursive equation, you: 1) Calculate the 1st term (this is often given to you).
