Q2) SPLIT every 3 terms
-5(First term) (-)1(second term) = -6(result 1) -5(First term) -6(result 1)= -11
23(2nd set first term)(-)29 (2nd set second term)=-6(result 1) 23(2nd set first term)-6(result)=17
by doing the above steps
-20 (-) -14=-6 -20 -6 = -26

Q.11) ( 2, 1/3, 2/3, 6) ,( 7, 1/2, 7/2, 14) ,( 20, 1/5, 4, ?)

the series must be divided in equal parts of 4 terms each,
First part
2*1/3=2/3
2*3=6
second part
7*1/2=7/2
7*2=14
third part
20*1/5=4
20*5=100


Hence 100 is the answer
