28 - 3 = 25 & 5.
21 - 3 = 18 & 5.
14 - 3 = 11 & 5.
21 - 3 = 18 & 5.
14 - 3 = 11 & 5.

28 - (25) =3 5 =25 5.
21 - (18) =3 5 =18 5.
14 - (?) =3 5 = ? 5.
= 14 - (11) = 3 5 = 11 5 (ans).
21 - (18) =3 5 =18 5.
14 - (?) =3 5 = ? 5.
= 14 - (11) = 3 5 = 11 5 (ans).

5 is here just to confuse us .
Subtracting 3 from alternative numbers that is;
28 - 25 = 3.
21 - 18 = 3.
14 - 11 = 3.
