What are Different Sum of Arithmetic Sequence Formulas? Thesum of the arithmetic sequence formula: when nthterm is not known: Sn= n/2 [2a + (n - 1) d] when nthterm(an) is known: Sn= n/2 [a1+ an] How to Use the Sum of Arithmetic Sequence Formula?
The result of the 1stformula is a dynamic spilled array, which is a great thing that saves you the trouble of copying the formula to other cells. The limitation is that dynamic arrays only work in a range, not a table. The 2ndand 3rdformulas return a single value, which a table can ...
Finding a formula for the nth term for a specific kind of sequence called a progression is possible. The most popular mathematical progression, with simple formulas, is the arithmetic progression (AP). A good example of an arithmetic progression (AP) is the sequence 3, 8, 13, 18, 23, 28...
Arithmetic Progression (AP) is a sequence of numbers in order that the common difference of any two successive numbers is a constant value. Learn with arithmetic sequence formulas and solved examples.
As the positive integral divisors would be the numbers which are products of one or more factors of the given number, we should first find out the factors of 540. Then, as we have to find out the sum of all the integral divisors and we know that each divisor will be...
1, 2, 3, 4,…., n this is an ap with first term a = 1 and last term l = n. we know that, the sum of n terms of ap when the first and last terms are known is given by: s = (n/2) (a + l) = (n/2)(1 + n) = n(n + 1)/2 therefore, the sum of the ...

Even though NOMA can improve spectrum efficiency of the system, it still cannot support the exponential increase of the system throughput. As such, multi-antenna technique and multi-user beamforming20 are applied for user access links to provide higher data rates. For example, to maximize the do...
