Given n and any number for the nth term, it is a simple matter to find a rule such that the above four numbers are the first four of a sequence and the given number in the nth position.
However, the simple answer for simple questions is Un = 4n
20
20
The nth term is: 4n
Please note that (a) this is a sequence of square numbes, and (b) the sequence starts at 22.
36 Seems like: 1 4 9 16 25 is squared sequence: 1 2 3 4 5 So 6 squared will be 36.
The nth term is 7n-5 and so the 6th term will be 37
You Have to use the Formula of: dn + (a-d). d= The difference in the sequence n= Stays how it is a= The first number in the Sequence. For Example: 4, 7, 10, 13, 16 3n + (4-3) So the answer is: 3n + 1 Hope it Helped By Jafar Abbas
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, ...
8 + 4n
The Nth term in the series is [ 2N ] .
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 is: 4n
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.
16
The nth term is equal to 4n.
6n+10

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