The nth term is (36 - 4n)

7n - 4

24 - 6n

Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...

If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .

The nth term is 7n-4 and so the next number in the sequence is 31

2n(n+1)

8 + 4n

The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.

If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .

If you mean: 34 39 24 ... then the nth term is 39-5n and so the 100th term = -461

While there are not enough terms to be fully certain, it appears that the following numbers in the sequence are being multiplied by the nth term. Therefore, 24 x 5 = 120 will be the next term in the sequence.

2n(n+1)

If you mean: 6 12 18 24 then the nth term is 6n

it is 3n^2+4n+4

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

The nth term of that series is (24 - 6n).

20, 21, 22, 23, 24, 25, 26, 27, 28, 29

The sequence progresses by adding 7 to the previous term.The nth term is thus equal to 10 + 7n. The 11th term therefore is equal to 10 + (7 * 11) = 10 + 77 = 87.

There are not enough numbers to be certain. The rule for the nth term could be Subtract 6 from the previous term giving 30, 24, 18, etc or Multiply previous term by 0.8 giving 30, 24, 21.6, etc etc

(n+1)^2 Please tell me you know what that means.

0,3,8,15,24,27,32,41

Given ANY number at all, it is possible to find a cubic polynomial such that that particular number is the nth number in a sequence starting with the above three. The simplest rule, however, is Un = 5n + 9

It goes up by (24-16) = 8 each time. The first time is 16. So the nth term is 8n + 8.
