show that the sum of the arithmetic means between two given quantities ,equidistant from the beginning and the end is constant.
I am not very clear about what is variable and what fixed here. Let's see if I can sort this out.
Let beginning = b
end = e
first quantity = a
second quantity = c
equidistant => a - b = e - c
=> a + c = e + b
So, if e and b are fixed it should be easy for you to finish this off.
sir here beginning and last numbers are constant,fixed.
plse explane in brief ,i m in trouble
That's what I was assuming.
b + e = constant => a+ c is constant.
All you need to fill in is the arithmetic mean. Do you know what that is?
