It is: 2n+4
2n - 12
The nth term is (2n - 12).
The nth term is equal to 4n.
The nth term of the sequence is expressed by the formula 8n - 4.
The nth term would be -2n+14 nth terms: 1 2 3 4 Sequence:12 10 8 6 This sequence has a difference of -2 Therefore it would become -2n. Replace n with 1 and you would get -2. To get to the first term you have to add 14. Therefore the sequence becomes -2n+14. To check your answer replace n with 2, 3 or 4. You will still obtain the number in the sequence that corresponds to the nth term. :)
28 - 8n
The nth term is: 3n+1 and so the next number will be 16
nth term is n squared plus three
The nth term of this sequence is 3n + 4
You can see that you add 10 to the previous term to get the next term. Term number 1 2 3 4 Term 4 14 24 34 You can also say: Term number 1 2 3 4 Term 0*10+4 1*10+4 2*10+4 3*10+4 So the nth term would be 10(n-1)+4 Or if you expand it, it's 10n-6
It is: 3n+1
T(n) = 12 - n2
The nth term is 2n
It is: 25-7n
The nth term of the sequence -4 4 12 20 29 is 8n+12 because each time the sequence is adding 8 which is where the 8n comes from. Then you take 8 away from -4 and because a - and - equal a + the answer is 12. Which is where the 12 comes from. Hope I helped.
7n - 4
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.
Un = 25 - 7n
-4-14112031 = -14112035 is a single number, not a sequence! It cannot have an nth term.
