(0 + 1 + 3 + 2) / 4 = 1.5
To find the average: add the four numbers in the question together, then divide the answer by 4. The zero can be ignored, but not the fact that there is a position occupied by a zero in the equation.
For instance, (1 + 3 + 2) / 3 = 2 So you can see there is a difference to the result.
Neither.
The arithmetic mean is 2.
It is an arithmetic sequence. To differentiate arithmetic from geometric sequences, take any three numbers within the sequence. If the middle number is the average of the two on either side then it is an arithmetic sequence. If the middle number squared is the product of the two on either side then it is a geometric sequence. The sequence 0, 1, 1, 2, 3, 5, 8 and so on is the Fibonacci series, which is an arithmetic sequence, where the next number in the series is the sum of the previous two numbers. Thus F(n) = F(n-1) + F(n-2). Note that the Fibonacci sequence always begins with the two numbers 0 and 1, never 1 and 1.

arithmetic sequence * * * * * A recursive formula can produce arithmetic, geometric or other sequences. For example, for n = 1, 2, 3, ...: u0 = 2, un = un-1 + 5 is an arithmetic sequence. u0 = 2, un = un-1 * 5 is a geometric sequence. u0 = 0, un = un-1 + n is the sequence of triangular numbers. u0 = 0, un = un-1 + n(n+1)/2 is the sequence of perfect squares. u0 = 1, u1 = 1, un+1 = un-1 + un is the Fibonacci sequence.
In ordinary arithmetic, the resulting value will be from an infinite set of values but in case modular arithmetic, resulting value will be from a finite set of values.Open in Google Docs ViewerOpen link in new tabOpen link in new windowOpen link in new incognito windowDownload fileCopy link addressEdit PDF File on PDFescape.come.g. in ordinary arithmetic, the sum of two integers, the result will be an integer in the range {..., -3, -2, -1, 0, 1, 2, 3, ...}for modular arithmetic, the sum of two integerslike (a+b)mod n will be in the range {0, 1, 2, ... n-1}
You can't 'invent' 1 + 1 = 2; it just does. On the contrary, 1 + 1 = 0 in mod(2) arithmetic 1 + 1 = 10 in base(2) arithmetic 1 + 1 = 1 in Boolean arithmetic 1 + 1 = [an arbitrary value] in group theory, depending on your choice of group. In fact, '1 + 1 = 2' is a consequence of selecting one particular set of rules to define one particular formal system. But there are lots of other systems that can be defined, and confusing 'Peano arithmetic' with 'mathematics' is like confusing 'Chess' with 'games'.
