What is the nth term for -1 -6 -11 - 16 -21?

The given sequence is -1, -6, -11, -16, -21. To find the nth term, we can identify that the sequence decreases by 5 each time. Thus, the nth term can be expressed as: ( a_n = -1 - 5(n-1) ), which simplifies to ( a_n = -5n + 4 ).

What is the nth term of -1-6-11-16-21?

The given sequence is an arithmetic sequence where each term decreases by 5. The first term (a) is -1 and the common difference (d) is -5. The nth term can be calculated using the formula ( a_n = a + (n-1)d ). Therefore, the nth term is ( a_n = -1 + (n-1)(-5) = -1 - 5(n-1) = -5n + 4 ).
