<u>ANSWER</u>: 110
<u>EXPLANATION</u>:
Let these five numbers be a, b, c, d and e.
Then "<span>arithmetic means of 5 numbers is 100" implies
(a + b + c + d + e) / 5 = 100
>> a + b + c + d + e = 500
</span>And "arithmetic means of 2 of these numbers (suppose a and b) is 85" implies
(a + b) / 2 = 85
>> a + b = 170
Using these two equations, we have
(a + b) + c + d + e = 500
>> (170) + c + d + e = 500
>> c + d + e = 500 - 170
>> c + d + e = 330
So "t<span>he mean of the other 3 numbers (c,d and e)" is
</span>(c + d + e) / 3 = 330 / 3 = 110
Hey there!
The formula is: y2 - y1 / x2 - x1
y2 = 11
y1 = 5
x2 = 4
x1 = 1
Equation: 11 - 5 / 4 - 1
11 / 5 = 6
6 / 4 - 1
4 - 1 = 3
6/3 = 2
