Here's one way:

multiples = []
(1..1000).each do |number|
  if (number % 2) == 0 && (number % 6) == 0
    multiples << number
  end
end
puts "multiples of 2 and 6 between 1 and 1000: #{multiples.join(', ')}"
print "sum of multiples: "
puts multiples.inject(0) { |sum, multiple| sum + multiple }

Regards,
Craig
