4. A very scared penguin has decided to go downhill skiing. When he is nervous he likes to do math. The ski lift starts at 100 feet from the bottom of the hill and will reach 1500 feet at the top. It goes up 200 feet per minute. How many minutes will the nervous penguin have to spend on the ski lift? Create an equation that represents this situation and solve it.

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
