A formula is a special type of equation that shows the relationship between different variables. A variable is a symbol like x or V that stands in for a number we don't know yet. Example: The formula for finding the volume of a box is: V stands for volume, l for length, w for width, and h for height.
Example 3: Find the explicit formula of the following arithmetic sequence; 11, 17, 23, 29, 35, 41, 47,â¦ Solution: First term a1 = 11, common difference d = 17 â 11 = 6. Use nth term formula to find the explicit formula. an = a1 + (n â 1)d. an = 11 + (n â 1)6. an = 11 + 6n â 6. an = 6n + 5. Therefore, explicit formula of the given arithmetic sequence is an = 6n + 5. Example 4: Find the explicit formula of the following geometric sequence; 3, 12, 36, 108, 432,â¦
