Q. Diego got a new video game. He scored 8 points on the first level, 4 points on the second level, 2 points on the third level, and 1 point on the fourth level. What kind of sequence is this?Choices:(A) arithmetic(B) geometric(C) both(D) neither
Identify Scores Sequence: Step 1: Identify the sequence of scores Diego got in each level: 8,4,2,1.
Check Arithmetic Differences: Step 2: Check if the sequence is arithmetic by finding the difference between consecutive terms.Difference between first and second levels: 8−4=4.Difference between second and third levels: 4−2=2.Difference between third and fourth levels: 2−1=1.Since the differences are not the same, the sequence is not arithmetic.
Check Geometric Ratios: Step 3: Check if the sequence is geometric by finding the ratio between consecutive terms.Ratio between first and second levels: 84=0.5.Ratio between second and third levels: 42=0.5.Ratio between third and fourth levels: 21=0.5.Since the ratios are the same, the sequence is geometric.
