If two numbers have arithmetic mean 2700 and harmonic mean 75, then find their geometric mean.
Note:
Clarification: The sum keeps alternating between two distinct positive numbers and two distinct negative numbers.
Real numbers form an arithmetic progression.
Suppose that Find the value of .
are terms in an arithmetic progression with common difference 1 such that their sum is 137.
What is the sum of the even terms of this progression? That is, what is the value of ?
You are given the sum of an arithmetic progression of a finite number of terms, as shown above.
What is the minimum number of terms used to make a total value of 513?
