Sal finds the 4th term in the sequence whose recursive formula is a (1)-, a (i)2a (i-1). Still, got questions? No problem! Don’t hesitate to comment below or reach out via email. Personally, I recommend looking at the arithmetic sequence or geometric sequence posts next! Looking to learn more about sequences? You’ve come to the right place! Check out these sequence resources and posts below. If you have a geometric sequence, the recursive formula is. If you have an arithmetic sequence, the recursive formula is. Starting at -16, each term has its sign reversed, and is divided by 4. Here, we are given the first term 1 3 together with the recursive formula. If you need to make the formula with a figure as the starting point, see how the figure changes and use that as a tool. By looking at the first three terms of the sequence, we can already see a pattern. To generate a sequence from its recursive formula, we need to know the first term in the sequence, that is. Think you are ready to solve a recursive equation on your own?! Try finding the specific term in each given recursive function below: Practice Questions: Solutions: Related Posts: Recall that a recursive formula of the form ( ) defines each term of a sequence as a function of the previous term.
