Step-by-step explanation:
Let x be the number
3 times the number = 3x

3x = 52 -7
3x = 45
x = 45/3
x = 15

As you can see the pattern here is add 9.
The 9th term will be 79.
The original value of x was negative, then –x, the opposite-signed version of x, would have to be positive. For instance, if I start with x = –3, then –x = –(–3) = +3, which is positive.
