Even or OddMy daughter and I once played a game based on the number 13 and the following rule:SponsoredThink of a positive whole number greater than 1. Apply another step to the outcome of the first step, and then further steps successively. For our game, we chose different starting numbers that were odd, and the winner was the person who by the fewer number of steps reached the number 1. My daughter won because she started with the number that leads to 1 in the fewest number of steps. What was my daughter’s starting number?
