Sum of Arithmetic Sequence Formula . The Arithmetic series of finite number is the addition of numbers and the sequence that is generally followed include – (a, a + d, a + 2d, …. and so on) where a is the first term, d is the common difference between terms. There are two popular techniques to calculate the sum of an Arithmetic sequence.

An “interest” problem – application of Geometric Series: Question A man borrows a loan of $1,000,000 for a house from a bank and likes to pay back in 10 years (120 monthly instalments), the first instalment being paid at the end of first month and compound interest being calculated at 6% per annum. Using the ∞ symbol, we can write the indicated sum of an infinite geometric series (with |r|1) by using summation notation as follows: a 1 +a 1 ⋅r+a 1 ⋅r 2 +⋯=∑ ∞ i=1 a 1 ⋅r i-1.

May 11, 2014 · The population of a local species of mosquitos can be found using an infinite geometric series where a1 = 740 and the common ratio is one sixth. Write the sum in sigma notation, and calculate the sum (if possible) that will be the upper limit of this pop Jul 31, 2005 · That sum is no easier to calculate than the original sum. (In fact, I would be able to figure out the original sum faster than the one in your last post) There are other ways to see how to approach this problem, but IMHO, writing it in sigma notation makes the right step much clearer.
a 4 = 18 ⋅ 3 = 54. a 5 = 54 ⋅ 3 = 162. Just as with arithmetic series it is possible to find the sum of a geometric series. It is found by using one of the following formulas: S n = a 1 − a 1 ⋅ r n 1 − r o r S n = a 1 ( 1 − r n) 1 − r. An infinite series is defined as the sum of the values in an infinite sequence of numbers. Assume the sequence n = 0 + 1 + 2 +3 + ….. which is undefined. The notation Sigma "Σ" is often used to represent the infinite series. The summation or sigma symbol means "sum up".
