3.12 Find the Term of the Sequence

  • Example 1:
    Find a53 term of the arithmetic sequence with a1 = 5 and a7 = 29.
    Given:
    First term = a1 = 5 and
    Seventh term = a7 = 29
    Find: a53
    Solution: Using the formula
    a7 = a1 + 6d
    29 = 5 + 6d
    24 = 6d
    d = 4
    a53 = a1 + 52.d = 5 + 52.4 = 213

  • Example 2
    Find the number of multiples of 9 between 30 and 901.
    The first multiple of 9 in the range is 36. a1 = 36
    The last multiple of 9 in the range is 900. an = 900
    Using the formula: an = a1 + d(n-1)
    900 = 36 + 9(n - 1) solving for n
    864 = 9n - 9
    873 = 9n
    n = 97
    Solution: There are 97 multiples in between 30 and 901
