Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
To solve this problem, we need to know the formula for the nth term of an arithmetic sequence. The formula is

= t₁ + (n-1)d, with

being the nth term, t₁ being the first term, and d being the distance between terms. Now we can substitute values to figure out what

is. When substituting, the equation becomes:

= 12 + 29(-6)

= -162
That means that the 30th term in this arithmetic sequence is
-162.
There can be so many of such.
Eg. 38 750 38 835
38 795
38 820
Any of the numbers above when rounded to the nearest hundred would result in 38 800.
The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.
Or if the 100 digit is already 8, then the 10 digit must be less than 5
