What is the nth term for 1 5 9 13 17?

This is an Arithmetic Series/Sequence. In general the nth term, A(n) = a + (n - 1)d....where a is the 1st term and d is the common difference. In this question, the 1st term equals 1 and the common difference is 4. Then the nth term, A(n) = 1 + (n - 1) x 4 = 1 + 4n - 4 = 4n - 3.


What is the nth term of 5 9 13 17?

The sequence 5, 9, 13, 17 is an arithmetic sequence where each term increases by 4. The first term (a) is 5, and the common difference (d) is 4. The nth term can be expressed using the formula: ( a_n = a + (n-1)d ). Therefore, the nth term is given by ( a_n = 5 + (n-1) \cdot 4 = 4n + 1 ).

What is the nth term rule of the linear sequence of -9-5-137?

To find the nth term of the linear sequence -9, -5, -1, we first identify the common difference between the terms. The difference between consecutive terms is 4. The first term (a) is -9, so the nth term can be expressed as ( a_n = -9 + (n-1) \cdot 4 ), which simplifies to ( a_n = 4n - 13 ).


What is the nth term of 1-5-9-13?

The sequence 1, 5, 9, 13 is an arithmetic sequence where the first term is 1 and the common difference is 4. The nth term can be found using the formula: ( a_n = a_1 + (n-1) \cdot d ), where ( a_1 ) is the first term and ( d ) is the common difference. Substituting the values, we get ( a_n = 1 + (n-1) \cdot 4 ). Simplifying this, the nth term is ( a_n = 4n - 3 ).

What is the nth term of the sequence 13 17 21 25 29?

The given sequence is an arithmetic sequence where each term increases by 4. The first term (a) is 13, and the common difference (d) is 4. The nth term can be found using the formula: ( a_n = a + (n-1)d ). Therefore, the nth term is ( a_n = 13 + (n-1) \cdot 4 = 4n + 9 ).
