Solution to Puzzle #151: Journey from 458 to 14

This was a simple puzzle and I got lots of correct answers. Ones to send correct answers were Suman Saraf’s daughter, Amit Mittal, Ram, Karan Sharma, Pratik Poddar, Ravish Aggarwal, Prakhar Prakash and Smiti Mittal. My elder one, Anisha, also solved this one.

It takes 8 steps to get to the answer. Trick was to get to 9 or 90 (or 18 or 180) and use the doubling function to get to 144 or 1440, and then truncate. There are many possibilities. Here is one:

458->45->90->9->18->36->72->144->14

Hope you all enjoyed the puzzle, and thanks again to Pooja Singh for sending the puzzle!
