Sum them : 340
Count them: 4 numbers
Divide sum by number of numbers = 340/4 = 85.
Alternatively, in this case, you may notice that the numbers are evenly spaced. The middle two numbers are 80 and 90 so halfway between then will be the overall mean. This only works for the arithmetic mean of evenly spaced numbers.
