The answer to this question is very intriguing but I would have to say it is unsolvable. have a good day
The most important variable is 4 miles per hour up hill. Down hill he can run 3 miles in the same time it takes time to run uphill. up hill 4 miles 1 hour so 2 miles up hill is 1/2 hour. Down hill he can run 3 miles in the same time it takes time to run up hill.. 2 miles up hill - 1/2 hour. So 1/2 hr up and 1/2 hr down = 1 hour.

<u>Given recursive formula</u>
a₁ = 0 aₙ = 2(aₙ₋₁)² - 1, for n>1 <u>The first 5 terms are:</u>
a₁ = 0 a₂ = 2(0)² - 1 = 0 - 1 = -1 a₃ = 2(-1)² - 1 = 2 - 1 = 1 a₄ = 2(1)² - 1 = 2 - 1 = 1 a₅ = 2(1)² - 1 = 2 - 1 = 1
