WebTo aid in teaching this, I'll use the following arithmetic sequence (technically, it's called a series if you're finding the sum):. Example A: #3 + 7 + 11 + 15 + 19 ... + t_20# Example B: #1 + 3 + 5 + 7 + 9 + 11 + 13 + 15# To start, you should know the following equations: WebExample 1: Find the value of n, if a = 10, d = 5, an = 95. Solution: Given, a = 10, d = 5, an = 95 From the formula of general term, we have: an = a + (n − 1) × d 95 = 10 + (n − 1) × 5 (n − 1) × 5 = 95 – 10 = 85 (n − 1) = 85/ 5 (n − 1) = 17 n = 17 + 1 n = 18 Example 2: Find the 20th term for the given AP:3, 5, 7, 9, …… Solution: Given, WebView history.
