(if you can me with this maybe you can me with my last posted question? it hasn't been answered and i need ! )

First, arrange your data from least (smallest number) to greatest (biggest number): {132,140, 142, 147, 149, 152, 158, 163, 165, 166, 168, 171, 173, 177, 178, 180, 180, 181, 182}
Second, subtract your greatest number from your smallest number: 182-132 = 50
Therefore, your answer is: 50

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'
