The unknown number n is 107.
A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
In order to find the number, we need to set up an equation where we represent the unknown number n as a variable.
18 more than that can be represented as n + 18.
We know it equals 125, so n + 18 = 125.
Subtract 18 from both sides:
n + 18 = 125
n + 18 - 18 = 125 - 18
n = 107
So our unknown number n is 107.
