Assuming 20 is n = 1, then the formula would be:
27-7n
The (n)th term = the (n - 1)th term + (2n + 1)
The nth term is: 5-6n
The nth term is: 3n+1 and so the next number will be 16
1+3n
I suspect that the first term should be "negative 3", ie the sequence is -3, 1, 5, 9, 13, 17, ... The nth term is 4n - 7
The (n)th term = the (n - 1)th term + (2n + 1)
The nth term is: 5-6n
The nth term is: 3n+1 and so the next number will be 16
what will the eight number be. 1, 7, 13, 19, 25, 31 ...
The given sequence is an arithmetic sequence with a common difference of 6. To find the nth term of this sequence, we can use the following formula: nth term = first term + (n - 1) x common difference where n is the position of the term we want to find. In this sequence, the first term is 1 and the common difference is 6. Substituting these values into the formula, we get: nth term = 1 + (n - 1) x 6 nth term = 1 + 6n - 6 nth term = 6n - 5 Therefore, the nth term of the sequence 1, 7, 13, 19 is given by the formula 6n - 5.
1+3n
The given sequence is 11, 31, 51, 72 The nth term of this sequence can be expressed as an = 11 + (n - 1) × 20 Therefore, the nth term is 11 + (n - 1) × 20, where n is the position of the term in the sequence.
I suspect that the first term should be "negative 3", ie the sequence is -3, 1, 5, 9, 13, 17, ... The nth term is 4n - 7
3n-2
2n+1
[ 25 - 6n ] is.
The nth term is 4n - 3
