The answer of this problem because i dont understand it

When we look at the table, we try to figure out the clues provided.  what we can see is on the first set of numbers...(2, 8)...the X value is 6 less than the Y value.  We next look at the next set of data...(3, 11)we see the X value is 8 less than the Y value.  So, if the first X value is 6 less and the second X value is 8 less, we can justify the X value for the third and fourth to be 10 and 12 less

I think the table should have data set  of
(2, 8)
(3, 11)
(4, 14)
(16, 26)
