continue a pattern:
1; 10;3; 30 __; __; __;
150; 140; 170; 160; __; __; __;
5; 25; 50; 10; __; __; __;
2; 5; 10; 3; __; __; __;
1; 300; 2; 600; __; __; __;

your question of
'continue a pattern' is much too vague.
for example in the first one it might appear that you start with odd numbers and follow it by 10 times that odd number.
so
1,10,3,30,5,50,...
or 101 = 9 = 3^2
30  3 = 27 = 3^3
then 86  5 = 3^4
so my pattern could have been
1,10,3,30,5,86,...
Do you see what I mean?
In what context was the question asked?
What are you studying to have these kind of questions?
What grade level is this?? 
Thanks. I'm in 5th grade. It was just math question to continue these and other simple pattern:
1; 10; 3; 30 __; __; __;
150; 140; 170; 160; __; __; __;
5; 25; 50; 10; __; __; __;
2; 5; 10; 3; __; __; __;
1; 300; 2; 600; __; __; __;
my answers
continue a pattern:
1; 10; 3; 30; 9; 90; 27
150; 140; 170; 160; 190; 180; 210;
5; 25; 50; 10; 50; 100; 20;
1; 300; 2; 600; 4; 1200; 8;
here no idea
2; 5; 10; 3; ?; ? ; ?
