Clearly, if you omit the sign, the nth. term will be 4n. The alternating sign can easily be expressed as a power of (-1), so in summary, the nth. term is (-1)n4n.

The nth term of a sequence is the general formula for a sequence. The nth term of this particular sequence would be n+3. This is because each step in the sequence is plus 3 higher than the previous step.

The nth term is: 4n

The nth term is equal to 4n.

16

8 + 4n

6n+10

n2

The nth term in the sequence means an unspecified number an unspecified distance along the series. 8 16 32 64 128... n. It is also a shothand notation so the reader knows that the sequence continues.

Please note that (a) this is a sequence of square numbes, and (b) the sequence starts at 22.

While there are not enough numbers to fully clarify the nth term of the sequence, according to the sequence so far it appears that the nth term is equal to n4. Therefore, the next number will equal 44 = 256

The Nth term in the series is [ 2N ] .

Un = 29 - 9n

Tn = 1 + 3n

1, 16, 81, 256 14641 is the 11th term.

The 8th term is 64. The sequence is the squares of the counting numbers. The nth term is given by t(n) = nÂ².

The nth term is 2n

The sequence is 2 larger than the 7 times table. The nth term can be expressed as 7n + 2.

2 + ((6 + 2 * (n - 1) * (n - 1))

The nth term of an arithmetic sequence is given by. an = a + (n – 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.

It means to find the generic expression for any term, not just for one specific term. For example, in the sequence 1, 4, 9, 16, 25... it should be clear that these are square numbers, which you can write as 12, 22, 32, etc. The nth. term is n2, meaning that for any number "n", term number n is n2.

The sequence S = 2, 2, 4, 6, 10, 16, 26, ... is the Fibonacci sequence multiplied by 2. Like the Fibonacci sequence, each term is found by adding the two previous terms, so Sn = Sn-1 + Sn-2.

The nth term is 3n+7 and so the next number will be 22
