The sum of the first n terms of an arithmetic progression is given by S_n = n2 − 8n. Find the least possible value of n such that the nth term is greater than 130.

The sum of the first $n$ terms is given by $S_n = n^2 - 8n$.
The $n$th term, $T_n$, can be found using the relationship $T_n = S_n - S_{n-1}$.
First, find $S_{n-1}$:

$$S_{n-1} = (n-1)^2 - 8(n-1)$$ $$S_{n-1} = (n^2 - 2n + 1) - (8n - 8)$$ $$S_{n-1} = n^2 - 2n + 1 - 8n + 8$$ $$S_{n-1} = n^2 - 10n + 9$$

Now, calculate $T_n$:

$$T_n = S_n - S_{n-1}$$ $$T_n = (n^2 - 8n) - (n^2 - 10n + 9)$$ $$T_n = n^2 - 8n - n^2 + 10n - 9$$ $$T_n = 2n - 9$$

The problem states that the $n$th term is greater than 130.

$$T_n > 130$$

Substitute the expression for $T_n$:

$$2n - 9 > 130$$

Add 9 to both sides of the inequality:

$$2n > 130 + 9$$ $$2n > 139$$

Divide by 2:

$$n > \frac{139}{2}$$ $$n > 69.5$$

Since $n$ must be an integer (as it represents the term number in a sequence) and $n$ must be greater than 69.5, the least possible integer value for $n$ is 70.

The least possible value of $n$ is $\boxed{70}$.
