Lexie is 6 years older than her brother and her sister is twice her age. If Lexie is 8, what is the age difference between her brother and her sister? Give me reasons, before answering the question
Lexie's brother is 8 - 6 = 2 years old. Her sister is 8 x 2 = 16 years old. The age difference between her brother and sister is 16 - 2 = 14 years. So the final answer is 14.
