Answer 1

Answer:

The spiral of Theodorus consists of right triangles, as in the diagram. If two sequences $a_{n}$ and $b_{n}$ are given by following conditions, find $a_{1}b_{1}+a_{2}b_{2}+...+a_{200}b_{200}$.

$a_{n}$ and $b_{n}$ is given by the sum and difference of the hypotenuse of a neighboring triangle, and $a_{1}=\sqrt{2} +1$, $b_{1}=\sqrt{2} -1$.
