WebWe can write an Arithmetic Sequence as a rule: xn = a + d (n−1) (We use "n−1" because d is not used in the 1st term). Example: Write a rule, and calculate the 9th term, for this … Websince the sequence is quadratic, you only need 3 terms. let x=the position of the term in the sequence let y=the value of the term the 1st term is 2, so x=1 and y=2 the 2nd term is 5, so x=2 and y=5 the 3rd term is 10, so x=3 and …

WebArithmetic Sequence. An arithmetic sequence is a sequence that has the property that the difference between any two consecutive terms is a constant. This constant is called the common difference. If a 1 is the first term of an arithmetic sequence and d is the common difference, the sequence will be: { a n } = { a 1, a 1 + d, a 1 + 2 d, a 1 + 3 ...
