title: Time complexity of a recursive function, using the Master's Theorem
body: <p>I need to find the time complexity of the function in the picture using Master's Theorem..
  I think the function is: T(n) = T(n-1) + c but it's impossible to solve using this theorem.
  Please help me I'm trying to solve it for 3 hours lol, thanks everyone!
