 Question: Arithmetic Sequence In an Arithmetic Sequence the difference between one term and the next is a constant. In other words, we just add the same value each time ... infinitely. In General we could write an arithmetic sequence like this: {a, a+d, a+2d, a+3d, ... } where: a is the first term, and d is the difference between the terms (called the "common difference") Rule We can write an Arithmetic Sequence as a rule: xn = a + d(n-1) Summing an Arithmetic Series  To sum up the terms of this arithmetic sequence: a + (a+d) + (a+2d) + (a+3d) + ... use this formula:    Question Given a 100 terms of arithmetic sequence, first term is  3, and the difference is 4, a new term is inserted between each tow terms and a new arithmetic sequence is received. What is the sum of terms of the new sequence? Question Created By: ali samhat Creation Date: 2017-05-29 16:18:29 View Question
