To arrange the planets in decreasing order of their strength of gravity based on Wayne's weight on each planet, we can compare the weight values and sort them accordingly.
Here are the planets arranged in decreasing order of gravity strength:
Jupiter: Wayne's weight on Jupiter is 333 pounds, which is the highest among the given planets.
Neptune: Wayne's weight on Neptune is 159 pounds, which is the second-highest weight.
Venus: Wayne's weight on Venus is 128 pounds, making it the third-highest weight.
Mars: Wayne's weight on Mars is 53 pounds, which is the lowest weight among the given planets.
So, the planets arranged in decreasing order of their strength of gravity based on Wayne's weight are: Jupiter, Neptune, Venus, and Mars.
