# Tough pattern questions

I can't fathom any kind of pattern in these questions. The test is over but i'm curious to know how it should be solved.

Given the combination of the two questions, I think the answers are:

B and D

## Explanation:

If we look at the

number of line segments in each image

we find that in the first image we have

2 2 4 6

which should be continued by

10 to form double the Fibbonaci sequence

and in the second image we have

8  6  5
12 10 9
4  3

which should have, in the bottom left corner

6 to keep the differences in each row/column constant between different rows/columns.

I also solved it the same way and got the same answer as the previous comment (without looking at theirs I mean). To elaborate further if you are still a bit confused, for the second problem you find the number of sides of each shape which are:

8  6  5
12 10 9
4  3


vertically, the difference between the first two numbers of each row is +4 and between the last two is -6. Horizontally the difference of the first two is -2 then -1. Therefore 12-6=6 or 4+2=6, so the answer has 6 sides. The only answer with six sides is number 4, the hexagon.
