If you mean: 6 12 18 24 then the nth term is 6n
The nth term of that series is (24 - 6n).
If you mean: 34 39 24 ... then the nth term is 39-5n and so the 100th term = -461
The nth term of an AP with initial term a (= u{1}) and common difference d is given by: u{n} = a + (n - 1)d In this case: a = 6 d = (12 - 6) = 6 → u{n} = 6 + (n - 1)6 But this can be simplified: u{n} = 6 + (n - 1)6 = 6 + 6n - 6 = 6n
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
24 - 6n
The nth term is (36 - 4n)
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, ...
2n(n+1)
8 + 4n
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
2n(n+1)
7n - 4
If you mean: 6 12 18 24 then the nth term is 6n
The nth term of that series is (24 - 6n).
The nth term is 7n-4 and so the next number in the sequence is 31
