Have a question about recursive methods

Given the following recursive function: public static int recur(int num) { if (num > 100) return num: else return recur((num * 2) + 3): } If the first call from within the main method is: int result = recur(4): What value will be passed as the num argument on the third call to recur (given that the call from within main is the first call)? ________. Using the recur function definition and call from the previous question, how many times will the recur function be recursively called before returning a result to the main method
