For the second week, Cody will log a total of 7 * 2,000 = <<7*2000=14000>>14,000 steps.
For the third week, Cody will log a total of 7 * 3,000 = <<7*3000=21000>>21,000 steps.
For the fourth week, Cody will log a total of 7 * 4,000 = <<7*4000=28000>>28,000 steps.
For the month, Cody will log a total of 7,000 + 14,000 + 21,000 + 28,000 = <<7000+14000+21000+28000=70000>>70,000 steps.
