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.
How to Calculate Sum of Terms from Pth to Qth Terms of Arithmetic Progression?
Sum of Terms from Pth to Qth Terms of Arithmetic Progression calculator uses Sum of Terms from Pth to Qth Terms of Progression = ((Index Q of Progression-Index P of Progression+1)/2)*((2*First Term of Progression)+((Index P of Progression+Index Q of Progression-2)*Common Difference of Progression)) to calculate the Sum of Terms from Pth to Qth Terms of Progression, Sum of Terms from Pth to Qth Terms of Arithmetic Progression formula is defined as the summation of the terms starting from the pth term to the qth term of given Arithmetic Progression. Sum of Terms from Pth to Qth Terms of Progression is denoted by Sp-q symbol.
