CompuChip said:What summation rule are you talking about?
What is n in your final answer?
How can it depend on i anyway, if you are summing over that?
Please elaborate a bit more on how you wanted to solve the question.
Summation is a mathematical process of adding together a sequence of numbers to obtain a total or sum. It is represented by the symbol Σ (sigma).
The purpose of summation is to simplify and condense a series of numbers into a single value. It is often used in mathematical and scientific calculations to analyze and interpret data.
To calculate summation, you need to add up all the numbers in the sequence. The formula for summation is Σx = x1 + x2 + x3 + ... + xn, where x1, x2, x3, ..., xn are the individual numbers in the sequence.
Summation and addition are similar in that they both involve adding numbers together. However, summation is used to add a sequence of numbers, while addition is used to add two or more individual numbers.
Summation has many real-life applications, such as calculating the total cost of a shopping trip, determining the average temperature over a period of time, or finding the total distance traveled on a road trip. It is also used in fields such as economics, physics, and engineering to analyze and interpret data.
