How to calculate the power consumption?

Power consumption: 1 degree = 1 kilowatt hour, which means that 1 kilowatt electrical appliances consume one degree of electricity continuously for one hour. Generally, electrical appliances are marked with power! For example, if a 60W bulb lights continuously for one hour, the power consumption is: 60W * 1 hour / 1000 = 0.06 degree

In order to understand the power situation in May, Xiao Ming observed and recorded the data displayed on his home appliance meter from May 1 to May 7, and calculated the average power consumption as the power consumption in May
For the calculation of electricity consumption, the degree displayed by the meter is as follows:
Date 1 2 3 4 5 6 7
Meter display 143 146 150 155 159 164 167
