  13. 13. Study the following sequence. 1, 2, 3, 4, 5,… 0, 5, 10, 15, 20, 25,… 5, 2, -1, -4, -7, -10,…
  14. 14. 1, 2, 3, 4, 5,… •The terms are obtain by adding 1 to each succeeding terms.
  15. 15. 0, 5, 10, 15, 20, 25,… •The terms are obtain by adding 5 to each succeeding terms.
  16. 16. 5, 2, -1, -4, -7, -10,… •The terms are obtain by adding –3 to each succeeding terms.or example the2nd term: 2 = 5+ (-3)
  17. 17. Definition: Arithmetic Sequence An arithmetic sequence is asequence in which each term after thefirst is obtained by adding the samefixed number, called the commondifference, to the preceding term.
  18. 18. 1, 2, 3, 4, 5,… •The terms are obtain by adding 1 to each succeeding terms.The common difference is d=1
  19. 19. 0, 5, 10, 15, 20, 25,… •The terms are obtain by adding 5 to each succeeding terms.The common difference is d=5
  20. 20. 5, 2, -1, -4, -7, -10,… •The terms are obtain by adding –3 to each succeeding terms.The common difference is d = -3
  21. 21. The common difference, d , of an arithmetic sequence:The nth term of an arithmetic sequence:
  22. 22. Illustrative Problem 1: Complete the arithmeticsequence, , up to 8 terms.Solution: Let , , .Then the common difference is
  23. 23. The first 8 terms of the sequence, using , are… The first 8 terms of the sequence are…
  24. 24. Illustrative Problem 2: Find the 25th term of the arithmetic series 2, 5, 8, 11, …
  25. 25. Illustrative Problem 3: Find the arithmeticseries of 6 terms if thefirst term is 27 and thelast term is 12.
  26. 26. Assignment: Solve the following problems 1. What are the first three terms of the arithmetic series whose 9th term is 16 and 40th term is 47? 2. The 18th and 52nd terms of an arithmetic series are 3 and 173, respectively. Find the 25th term. 3. Find the sum of all odd integers from 27 to 495, inclusive. 4.
