The sum of an arithmetic series where a= 32, d=1, and n=22 is ( )A. 264B. 24C.
An arithmetic sequence refers to a series of numbers separated by a constant difference between adjacent terms. The formula used to solve the sum of an arithmetic sequence is: n/22a + (n-1)d, where n = the number of terms to be added, a = the first term, and d = the constant val...
Determine the sum of the following arithmetic series. 3 + 9 + 15 + ... + 63 Arithmetic Series In mathematics, if a series of numbers is generated by adding a common value or a constant value to each of the preceding terms, the series formed is known as an ...

How do I calculate the sum of a series? Many a time, we'd want to calculate thesumof a series, and in order to do that, it helps to first know if the series isarithmeticorgeometric. In anarithmetic series, thedifference between each pair of successive terms is constant, while in a...
first term in the sequence S10=10(2+29)/2 a n = the last term in the sequence S10=10(31)/2 S10=310/2 S10=155 So, the sum of the first 10 terms of the arithmetic series that begins at 2 and has a common difference of 3 is 155....
