) formula or explicit equation, for which it suffices to know one term of the sequence and the common difference or common quotient, whose meanings will be explained in the next sections, where we will see the explicit formula for arithmetic sequence and explicit formula for geometric sequence....
Apart from, the explicit formulas of arithmetic, geometric, and harmonic sequences, there can be any other formulas. For example, the explicit formula for the sequence 1, 4, 9, 16, 25, ... is an = n2 as every term is a square number of its position.☛...
For the infinite number of terms, we have much more compact formula as: S∞=a11−rfor,r<1 AndS∞=a1r−1for,r>1 Solved Examples for Geometric Series Formula Q.1: Add the infinite sum 27 + 18 + 12 + … Solution: It is a geometric sequence. So using Geometric Series Formula Here...

Sequences that are built from multiplying or dividing each previous term are referred to as geometric sequences, and a different formula is used. Writing Formulas for Arithmetic Sequences Sample Questions Here are a few sample questions going over writing formulas for arithmetic sequences. Question ...
Geometric Progression Definition A geometric progression is a sequence in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. For example, the sequence 1, 2, 4, 8, 16, 32… is a geometric sequence ...
The summation formulas are used to calculate the sum of the sequence. There are various types of sequences such as arithmetic sequence, geometric sequence, etc and hence there are various types of summation formulas of different sequences. Also, there are summation formulas to find the sum of ...
The invention of logarithms was foreshadowed by the comparison ofarithmeticand geometric sequences. In a geometric sequence each term forms a constantratiowith its successor; for example,…1/1,000, 1/100, 1/10, 1, 10, 100, 1,000…has a common ratio of 10. In an arithmetic sequence eac...
Geometric mean is a mean or average, defined as the nth root of the product of the n values for the set of numbers. Learn formulas, properties, applications, and examples at BYJU’S.
