Answer 1

The pattern in Lincoln's earnings shows a weekly increase of $60. By reversing this pattern, we subtract $60 from his week 1 earnings to find that he would have started out with $60 at week zero.

Step-by-step explanation:

Lincoln has kept a record of his earnings over four weeks, showing an increase each week. To determine what amount he would have started out with (at week zero), we can use the information given:

• Week 1: $120
• Week 2: $180
• Week 3: $240
• Week 4: $300

By examining the pattern, we see that Lincoln's earnings increase by $60 each week ($180 - $120 = $60, $240 - $180 = $60, etc.). If we reverse this pattern to find out his earnings at week zero, we subtract $60 from his week 1 earnings of $120. Thus, at week zero, Lincoln would have started out with $120 - $60 = $60.
