Question

if the letter n represents a positive integers {1,2,3,4. . .}, write algebraic expression for each of the following
the integers preceding n

Answer 1

The integers preceding a positive integer \( n \) can be represented by the expression \( n - 1 \).

If you want to refer to multiple preceding integers, you could express them as:

- The first integer preceding \( n \): \( n - 1 \)
- The second integer preceding \( n \): \( n - 2 \)
- The third integer preceding \( n \): \( n - 3 \)

And so forth. In general, the \( k \)-th integer preceding \( n \) can be represented as:

\[
n - k
\]

where \( k \) is a positive integer (1 for the first preceding integer, 2 for the second, etc.).
