Dampened spring problem

Trying to solve this problem but can't figure it out.

I've tried using the energy equation to solve for the amplitude but there are to many unknowns to deal with.

A mass on a spring oscillates in damped harmonic motion with initial amplitude 12.2 cm. After five complete oscillations, the system has lost 50% of its initial energy. What is the amplitude of the oscillation after the system has undergone ten complete oscillations?
You may assume that b2 << km.

What are b2 and km?

You shouldn't just assume we are familiar with all the naming conventions that you are using.

By the way, the spring is "damped" not "dampened" (no one sprinkled it with water).
