What is the formula for the nth term for the sequence 12-21-30-39-48?
> since the value rises by nine at each step and the first term is 12 the formula for > the nth term is: 12+(n-1)*9 Which simplifies to Sn = 9n + 3
What is the 20th term for the sequence 3 6 9 12?
It is 60.
What is the nth term of this sequence 2 7 12 17 22?
5
What is the nth term of the sequence 2 7 12 17?
The nth term is 5n-3 and so the next term will be 22
What is the 33rd term of this arithmetic sequence 12 7 2 -3 -8 and?
It is -148.
What is the value of the 11th term in the sequence 3 6 12 24?
It is: -3072
What is descending geometric sequence?
A geometric sequence is a sequence where each term is a constant multiple of the preceding term. This constant multiplying factor is called the common ratio and may have any real value. If the common ratio is greater than 0 but less than 1 then this produces a descending geometric sequence. EXAMPLE : Consider the sequence : 12, 6, 3, 1.5, 0.75, 0.375,...... Each term is half the preceding term. The common ratio is therefore ½ The sequence can be written 12, 12(½), 12(½)2, 12(½)3, 12(½)4, 12(½)5,.....
What is the value of the 11th term in the sequence -3 -6 -12 -24?
This is a geometric series with common ratio 2. The nth term is un = -3*2(n-1) So u11 = -3*2(11-1) = -3*210 = -3*1024 = -3072
What is the value of the nth term in the following arithmetic sequence 12 6 0 -6 ...?
18 - 6n
Nth term of the sequence 12 7 2 -3 .. I know what the next numbers in the sequence are but what is the expression for the nth term?
12 - 5(n-1)

Which sequence follows the rule 8n-4. where n represents the position of a term in the sequence?
12
Is geometric sequence a sequence in which each successive terms of the sequence are in equal ratio?
Yes, that's what a geometric sequence is about.
What is the nth term of the sequence -4 4 12 20 29?
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.
What is the 12th term of a geometric sequence in which the common ratio is 2 and the first term is 12?
36
What is the 20th term for the sequence 3 6 9 12?
It is 60.
What is the d value of the following arithmetic sequence 16 9 2 5 12 19?
The sequence in the question is NOT an arithmetic sequence. In an arithmetic sequence the difference between each term and its predecessor (the term immediately before) is a constant - including the sign. It is not enough for the difference between two successive terms (in any order) to remain constant. In the above sequence, the difference is -7 for the first two intervals and then changes to +7.
