Sum of Last N Terms of Arithmetic Progression given Last Term Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sum of Last N Terms of Progression = (Index N of Progression/2)*((2*Last Term of Progression)+(Common Difference of Progression*(1-Index N of Progression)))
S_n(End) = (n/2)*((2*l)+(d*(1-n)))
This formula uses 4 Variables

Variables Used

Sum of Last N Terms of Progression - The Sum of Last N Terms of Progression is the summation of the terms starting from the end to the nth term of a given Progression.
Index N of Progression - The Index N of Progression is the value of n for the nth term or the position of the nth term in a Progression.
Last Term of Progression - The Last Term of Progression is the term at which the given Progression terminates.
Common Difference of Progression - The Common Difference of Progression is the difference between two consecutive terms of a Progression, which is always a constant.

STEP 1: Convert Input(s) to Base Unit

Index N of Progression: 6 --> No Conversion Required
Last Term of Progression: 100 --> No Conversion Required
Common Difference of Progression: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_n(End) = (n/2)*((2*l)+(d*(1-n))) --> (6/2)*((2*100)+(4*(1-6)))

Evaluating ... ...

S_n(End) = 540

STEP 3: Convert Result to Output's Unit

540 --> No Conversion Required

FINAL ANSWER

What is an Arithmetic Progression?

An Arithmetic Progression or simply AP is a sequence of numbers such that successive terms are obtained by adding a constant number to the first term. That fixed number is called the common difference of the Arithmetic Progression. For example, the sequence 2, 5, 8, 11, 14,... is an Arithmetic Progression with first term is 2 and common difference is 3. An AP is a convergent sequence if and only if the common difference is 0, otherwise an AP is always divergent.
