Example: Writing Terms of Arithmetic Sequences Givena1=8a1=8anda4=14a4=14, finda5a5. Show Solution The sequence can be written in terms of the initial term 8 and the common differenced. {8,8+d,8+2d,8+3d} We know the fourth term equals 14; we know the fourth term has the forma1...
The formula provides an algebraic rule for determining the terms of the sequence. A recursive formula allows us to find any term of an arithmetic sequence using a function of the preceding term. Each term is the sum of the previous term and the common difference. For example, if the common...
Example 17: The sum of the first n terms of the arithmetic sequence {$$ a _ { n } $$} is $$ S _ { n } $$. The sum of the first n terns of the arithmetic sequence |$$ b _ { n } $$} is $$ T _ { n } $$. Find a$$ \frac { a _ { 6 } } { b _ { 6 ...

A sequence of number is called arithmetic if it consists of at least three elements and if the difference between any two consecutive elements is the same. For example, these are arithmetic sequence: 1, 3, 5, 7, 9 7, 7, 7, 7
Example: Add up the first 10 terms of the arithmetic sequence: { 1, 4, 7, 10, 13, ... } The values of a, d and n are: a = 1 (the first term) d = 3 (the "common difference" between terms) n = 10 (how many terms to add up) So: Becomes: = 5(2+9·3) = 5(29)...
