Question

pls help me. urgent guys please
Solve the pattern-3,10,6,20,9,30

Answer 1

It has been like this
3+7=10
10-4=6
6+(7*2)=20
20-(7+4)=9
9+(7*3)=30
30-(7+7+4)=12
12+(7*4)=40
So answer is 12 40

Answer 2

look the pattern, terms in the odd position are multiple of 3 ( 3,6,9 so the next is 12)
terms in even position are multiples of ten (10,20,30 so the next is 40)
