You can see that all the numbers go up by 7. This means that the first part of the nth term rule for this sequence is 7n. Now, you have to find out how to get from 7 to 3, 14 to 10, 21 to 17 ... this is because we are going up in the 7 times table. To get from the seventh times table to the sequence, you take away four. So the answer is : 7n-4

Well, honey, it looks like we've got ourselves an arithmetic sequence with a common difference of 7. So, the nth term formula for this sequence is: nth term = 3 + 7(n-1), where n is the position of the term in the sequence. Just plug in the position you want, and you'll have your answer faster than you can say "Golden Girls marathon."
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
3(2^n-1) * * * * * Nearly, but not quite. The correct answer is 3*2n
The pattern is: +11, +15, +19, +23, +27 (4n+7) So, the next number would be: (4*6 + 7) = 24 + 7 = +31 Therefore, the answer is: 105 + 31 = 136
