create an algorithm that requests to enter two numbers, between the range of those numbers that is displayed only multiple of 7

function multi7(a, b){
  var result = [];
  for (var i = a; i <= b; i++){
    if (i%7 == 0) {
      result.push(i);
    }
  }
  return result;
}
var numbers = multi7(1, 100);
