First Term of Arithmetic Progression given Pth and Qth Terms Solution

STEP 0: Pre-Calculation Summary
Formula Used
First Term of Progression = (Pth Term of Progression*(Index Q of Progression-1)-Qth Term of Progression*(Index P of Progression-1))/(Index Q of Progression-Index P of Progression)
a = (Tp*(q-1)-Tq*(p-1))/(q-p)
This formula uses 5 Variables
Variables Used
First Term of Progression - The First Term of Progression is the term at which the given Progression starts.
Pth Term of Progression - The Pth Term of Progression is the term corresponding to the index or position p from the beginning of the given Progression.
Index Q of Progression - The Index Q of Progression is the value of q for the qth term or the position of the qth term in the Progression.
Qth Term of Progression - The Qth Term of Progression is the term corresponding to the index or position q from the beginning of the given Progression.
Index P of Progression - The Index P of Progression is the value of p for the pth term or the position of the pth term in the Progression.
STEP 1: Convert Input(s) to Base Unit
Pth Term of Progression: 50 --> No Conversion Required
Index Q of Progression: 8 --> No Conversion Required
Qth Term of Progression: 80 --> No Conversion Required
Index P of Progression: 5 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
a = (Tp*(q-1)-Tq*(p-1))/(q-p) --> (50*(8-1)-80*(5-1))/(8-5)
Evaluating ... ...
a = 10
STEP 3: Convert Result to Output's Unit
10 --> No Conversion Required
FINAL ANSWER
10 <-- First Term of Progression
(Calculation completed in 00.004 seconds)

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.
