Anything in parenthesis is actually subscripted. If you could answer the problem for me that might be cool, too.

1) Consider the arithmetic sequence A = { An } determined by the conditions
A(n+1) - A(n) = 2
A(0) = 1
Work out the first 3 terms of the sequence and enter them below.
Separate the terms of the sequence by commas: 15, -3, 11, etc.

1) Oil spilled from a ruptured tanker spreads in a circle at a constant rate of 6 miles^2/hr. How fast is the radius of the spill increasing when the area is 9mi^2?

2) a 17 ft ladder is leaning against a wall. If the bottom of the ladder is pulled along the ground away from the wall at a constant rate of 5 ft/sec., how fast will the top of the ladder be moving down the wall when it is 8 ft above the ground?

If anybody can answer these questions and explain step by step in detail, you are a genius!!
