Hope this helps, I didn't know if that seventy was positive or negative so I did both scenarios.

Step-by-step explanation:

The range is the difference between the largest and smallest number

-80  -72  -69  -66  -66  -61  70

If you mean for this seventy to be positive then the range is 150

-80  -72  -70  -69  -66  -66  -61

If it is not positive and you forgot to put the negative sign then your answer is 19
