2n+3. If 5 is the first term, then it is 2n + 3 (2×1 = 2 + 3 = 5 and 2×2 + 3 = 7)
7 - 4n where n denotes the nth term and n starting with 0
The nth term in the sequence -5, -7, -9, -11, -13 can be represented by the formula a_n = -2n - 3, where n is the position of the term in the sequence. In this case, the common difference between each term is -2, indicating a linear sequence. By substituting the position n into the formula, you can find the value of the nth term in the sequence.
Un = (-1)n*(2n - 1)
(2n-1)(-1)n
fu
The nth term of the sequence is 2n + 1.
Un = 4n - 9
The "N"th term is -7. You can deduce this from: 19 - 7 = 12 - 7 = 5 - 7 = -2 - 7 = -9
7 - 4n where n denotes the nth term and n starting with 0
For an A.P., nth term of the sequence is given by 5 + (n-1)d, where d is the common difference.
The nth term is 7n-5 and so the 6th term will be 37
2n + 1
It is: nth term = 7n-9
The nth term in the sequence -5, -7, -9, -11, -13 can be represented by the formula a_n = -2n - 3, where n is the position of the term in the sequence. In this case, the common difference between each term is -2, indicating a linear sequence. By substituting the position n into the formula, you can find the value of the nth term in the sequence.
2n+5
The nth term is: 2n+7 and so the next number will be 19
Un = (-1)n*(2n - 1)
