👉 Decurrences are a type of recurrence relation that describes how an expression or sequence of expressions repeats itself over time. In other words, it is a mathematical equation where one variable in an expression is repeatedly multiplied by another variable until reaching a particular value.
For example:
1. 5
x = 20 (where x represents the number)
2. 3
y = 9 (where y represents the number)
In both cases, the base case of the decurrences equation is when
