Question

why the nth term of an AP should be positive integer
​

Answer 1

Answer:

For example, the sequence 9, 6, 3, 0,-3, .... is an arithmetic progression with -3 as the common difference. The progression -3, 0, 3, 6, 9 is an Arithmetic Progression (AP) with 3 as the common difference. ... Thus nth term of an AP series is Tn = a + (n - 1) d, where Tn = nth term and a = first term.

Answer 2

Step-by-step explanation:

no need to be the nth term of an AP to be positive

for example look at the below A. P

9,7,5,3,1,-1,-3

now if you see if I want to find the next term let's that is the nth term, it is not positive right

so no need to be positive
