Very simple - it was the next mission in the series after Apollo 7.
One of the crew members - James Lovell - drew a sketch from which the mission patch was made. It showed the path of the spacecraft, going off to the Moon and returning to Earth describing a figure of 8. Lovell knew that the actual flight path wouldn't be an exact figure of 8, but it was descriptive of the aim of the mission - to fly to the Moon and return - and was a very visual way of including the mission number.
It was called Apollo 8.
The astronaut of Apollo 8 and Apollo 13 was James Lovell.
Apollo 8 went around the moon, but Apollo 11 landed on the moon, it was called Eagle
Apollo 9 followed Apollo 8.

The Apollo 8 was the first to look at the face of the earth ;)
Apollo 9 followed Apollo 8.
Apollo 13, Apollo 1, Apollo 8, Apollo 10 and maybe some other ones. But missions Apollo 8 and Apollo 10 weren't planned to go to the moon. They were just preparing for Apollo 11.

Apollo 8 did not blow up. Apollo 8 was the first manned spacecraft to orbit the moon. It returned to the Earth safely. Apollo 13 is the spacecraft that had an explosion while traveling to the moon.
Apollo 8 carried the first men to ever orbit the moon.
Apollo 8 brought silly putty to alleviate boredom.
