Question

Given the numbers: $6,7,18,22$. What number must be subtracted from each of the following numbers, so that they will be in proportion?

Answer 1

If we subtract $2$ from $6,1$ from $7,10$ from $18$ and $12$ from $22$

Then the numbers become $4,6,8,10$ which are in A.P

Therefore the numbers needed to be subtracted are $2,1,10$ and $12$ respectively
