What is a Geometric Progression?
In Mathematics a Geometric Progression or simply GP also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed real number called the common ratio. For example, the sequence 2, 6, 18, 54,... is a Geometric Progression with common ratio 3. If the sum of all terms in the progression is a finite number or if the infinite sum of the progression exists then the we say it is an Infinite Geometric Progression or Infinite GP. And if the infinite sum of the progression does not exist, then it is a Finite Geometric Progression or Finite GP. If the absolute value of the common ratio is greater than 1 then the GP will be a Finite GP and if it is less than 1 then the GP will be an Infinite GP.
How to Calculate Nth Term from End of Geometric Progression given Last Term?
Nth Term from End of Geometric Progression given Last Term calculator uses Nth Term from End of Progression = Last Term of Progression/(Common Ratio of Progression^(Index N of Progression-1)) to calculate the Nth Term from End of Progression, The Nth Term from End of Geometric Progression given Last Term formula is defined as the term corresponding to the index or position n starting from the end of the given Geometric Progression, calculated using the last term. Nth Term from End of Progression is denoted by Tn(End) symbol.
