EXAMPLE

Start on the first number (2), underline it and jump over the next 2 numbers; you land on (3) which you underline and leave by jumping over the next 3 numbers; you land on (5) which you underline and leave by jumping over the next 5 numbers; you land on (7) which you underline and leave by jumping over the next 7 numbers; you land on (11) etc. The underlined numbers show the succession of the prime numbers. If you now erase all those underlined numbers the resulting sequence is the one you started with.
