    - The next two numbers will be 36 and 44

    - The 12th number will be 78

    - The 100th will be 694

    - The expression is 7n-6

    The relationship just seems to be what I said before, 7n-6, I don't really know what they mean. Unless of course, they want you to say it's a geometric sequence.

    relationship is the next number is 7 greater that the previous

    next 2 number are 36, 43

    12th number will be 78

    dn + (a-d)

    d = common difference a = first term

    (7)(12) + (1-7)

    84 + -6

    84 - 6 = 78

    100th term

    dn + (a-d)

    (7)(100) + (1-7)

    700 - 6

    694

    the sequence is n = 7.

    the next two numbers are 36 and 43.

    78 is the 12th number of the sequence.

    1) +7 (add 7)

    2) 36 and 43

    3) 78

    4) 694

    5) dn + ( a - d ) where D is the common difference and A is the first term and N is the term you want to find

    You must be a pretty stupid 8th grader because I am in 6th grade and I know what all the answers are

    1) +7

    2) 36 and 43

    3) 78

    4) 694

    5) 7n-6

    You will not learn if I or anyone else gives you the answer. I will, however, give you a hint: 7.
