Question

Can some one help me with these word pattern problems?

Answer 1

I think the first one is D 900

Answer 2

The "First Difference" will help you a lot.

Here's the list.
6075
4050
2700
1800
1200

Here are the "first differences"

4050 - 6075 = -2,025
2700 - 4050 = -1,350
1800 - 2700 = -900
1200 - 1800 = -600

Do you see a pattern? I don't. Let's do it again. "2nd Differences"

-1350 - (-2025) = 675
-900 - (-1350) = 450
-600 - (-900) = 300

How about now? Still kind of vague. Let's do it again. "3rd differences"

450 - 675 = -225
300 - 450 = -150

I'm not sure we are seeing a useful pattern, here. We could calcualte 4th differences and SAY we found a pattern. Let's try rations, instead.

Here's the list.
6075
4050
2700
1800
1200

1st Ratios
4050/6075 = 2/3
2700/4050 = 2/3
1800/2700 = 2/3
1200/1800 = 2/3

I think we found a pattern. Guess 1200*(2/3) = 800

Answer 3

Sometimes, you just have to explore a little.

Answer 4

thank you so much :)

Answer 5

* ratios

not "rations".
