I have a problem that I hope someone can answer. If you had 10 couples walk to a continent who had a life span of 50 years and had 3 children per couple per generation. What would be the population after 50000 years ?

If the continent had a lifespan of 50 years, the population would be 0 unless they could swim.

If you're talking about the people, their lifespan is less important here than at what age they reproduced, on average.
