To find the next number, subtract the smaller number from the bigger number.
I will show you with the firsttwo questions.
Continue a pattern:
1; 10; __; __; __;
10  1 = 9.
The pattern is 9 more than the previous term.
10 + 9 = 19
19 + 9 = 28
28 + 9 = 37
Here is the entire set:
1; 10; 19; 28; 37
=====================================
150; 140; 170; 160; __; __; __;
From 150 to 140, there is a drop of 10.
From 140 to 170, there's an increase of 30.
From 170 to 160, another drop of 10.
What do you think comes next?
Here is the pattern:
drop 10, add 30, drop 10, add 30, etc.
We add 30 to 160 and get 190.
We now subtract 10 from 190 and get 180.
We now add 30 to 180 and get 210.
Here is your entire set:
150; 140; 170; 160; 190; 180; 210
Do the same for the remaining questions.
