It’s Double Time | Cyberchase
In this Cyberchase clip, the Cybersquad beats Hacker to the top of a building because the number of stairs they can climb doubles at each level, while Hacker's are increasing steadily by one step each time. Inez calculates this rate of change and explains that even though they were behind Hacker at the beginning of the chase, they won due to the rate of growth.
