This sequence has a difference of 5 between each number. The values of a and d are: a = 3 (the first term) d = 5 (the "common difference") Using the Arithmetic Sequence rule: xn = a + d(n−1) = 3 + 5(n−1) = 3 + 5n − 5 = 5n − 2 So the 9th term is:...

We have been given a sequence 1, 2, 3, 4, 5, ………. anwhich has 15 terms and we are required to find the nth term of this sequence. Let us summarise this information in mathematical terms. We have, Number of terms, n = 15 First...
Processing, display, and communication of digital information, that is, information encoded as numbers is accomplished by arithmetic with various kinds of numbers. Such computations are performed with algorithms that are sequences of operations with numbers such as addition, multiplication, and reading ...
Then take the fourth term in your sequence and subtract it from the third term. Repeat this process until you have found the difference between each number within your sequence. Take a look at the following example. Find the common difference example. Using the given sequence, find the common...

For example, to find the 11th term in an arithmetic sequence that starts with 2 and has a common difference of 3, the 2 (first term) is added to 10 times 3, the common difference. What is the arithmetic sum formula? The arithmetic sum formula sums up a finite number of terms in an...
