<em>Answer</em></h2>
<em>361</em><em>π</em><em>km²</em>
<h2>
<em>Explanation</em></h2>
• the formula to find the area of a circle is A=πr²
<h3> =>
<em>A=π(19km)²</em></h3><h3>
<em>A=π(19km)² => A=361πkm</em>²</h3><h2>

Assuming that f(n+1) = f(n) is the full recursive definition, and that there are no typos, then this means that the nth term is equal to the (n+1)th term for any n where n is a positive whole number.
So
f(1) = f(2)
f(2) = f(3)
f(3) = 9
By the transitive property, f(1) = f(3) = 9. Therefore the answer is 9.
A1 represents the first term
d represents the common difference.....and since the common difference is 3, u have to add 3 to each term to find the next term....because with an arithmetic sequence u add to find the next term, whereas, in a geometric sequence u multiply to find the next term
5...first term
5 + 3 = 8...2nd term
8 + 3 = 11...3rd term
11 + 3 = 14...4th term
ur answer is B
