Explanation

This looks like an arithmetic sequence problem.
If the first term $a = 3$ and last term $l = 18$, and there are 4 numbers in between, the total terms $n=6$ (3 + 4 + 18).

The terms:
$a_1 = 3$
$a_6 = 18$
Number of terms $n = 6$

Common difference $d = frac{18 - 3}{6 - 1} = frac{15}{5} = 3$

The 3rd middle number is the 4th term:
$a_4=a_1+3d=3+3\times 3=12$

Explanation

Explanation

Equating the two expressions and simplifying gives:

$$x cdot 200 = y cdot 250 Rightarrow frac{y}{x} = frac{200}{250} = frac{4}{5} Rightarrow y : x = 4 : 5$$

⇒y​/x=200/250

=4​/5

⇒y:x=4:5
