How old is Lexie's brother? ** Lexie's brother is 8 - 6 = <<8-6=2>>2 years old.
How old is Lexie's sister? ** Her sister is 8 x 2 = <<8*2=16>>16 years old.
What is the age difference between her brother and sister? ** The age difference between her brother and sister is 16 - 2 = <<16-2=14>>14 years.
