You have to log every number from 4 to 156.Here you are adding numbers like 4+5+6.... to your number variable. You just have to output the numbers. That can be done simply by

for (var i = 4; i <= 156; i++) {
  console.log(i);
}

And one more thing your number variable is a empty string not a number. You just declare a number by

var var_name = your_number;
//or declare the variable and assign it afterwards
var number;
number = 1;
