Puzzle #45: Prime Numbers

Beautiful puzzle I got today, attributed to my niece, Radhika. Got this puzzle from her Maths Olympiad book for Grade 7. Puzzle is solvable by all kids in grade 4 and above.

Here is the question – Arrange numbers 1 through 71 in a sequence, such that sum of any two consecutive digits in the sequence is a prime number.

Hint – For younger children, i.e. grade 4 and 5, try the same question for a sequence from 1 through 17.

As always, please send your answers directly to me at alokgoyal_2001@yahoo.com. If you like the puzzle, please share it with others. If you have interesting puzzles to share, please send them to me at my e-mail given above.

Happy sequencing!
