Jensen wants to see if wearing his newly purchased step counter will motivate him to walk at least 200 steps more than the previous day.

On the first day, he walks 4,000 steps.

On the second day, he walks 4,200 steps.

On the third day, he walks 4,700 steps.

On the fourth day, he walks 4,200 steps.

Jensen: “I walked less on the fourth day compared to the other days. I guess the step counter doesn’t motivate me to walk more.”
