Recursive formulas can make calculating sequences much easier, especially in Grade 10 Pre-Calculus. Here’s why I think they are really helpful:
Step-by-Step Building: You figure out each term by looking at the one before it. This helps you see the pattern better.
Less Mental Math: Instead of using a complicated formula, you just keep adding or multiplying based on the starting point.
For example, if you have a sequence like ( a_n = a_{n-1} + 2 ), you simply add 2 to the last term you found. This way of working feels more natural!
