- 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.
