Ella is flying a kite in an open field. She starts with her kite at an altitude of 60 meters above the ground. Every hour, the altitude of her kite increases by 15 meters.
Let h(n) represent the altitude of Ella's kite at the beginning of the nth hour.
a. Is it arithmetic or geometric?
b. Write in explicit formula.
a. The altitude of Ella's kite is increasing by a constant amount with each hour, therefore it is an arithmetic sequence.
b. The explicit formula for the altitude of Ella's kite at the beginning of the nth hour can be written as:
h(n) = 60 + 15n
This formula represents the arithmetic sequence where the initial altitude is 60 meters and the altitude increases by 15 meters every hour.
