- All answers are:-
1) [1 1/2 3/2 2] [5 1/3 16/3 15] [12 1/4 49/4 ?]
1st term+ 2nd term=3rd
1st term / 2nd term=4th
ans is 48
2)[48 24] [35 7] [16 8] [75 15] [80 ?]
48/2=24
35/5=7
16/2=8
75/5=15
80/2=40
ans =40
3) [-27 9 -3[ [81 -27 9] [54 ? ?]
-3*-3=9
9*-3=-27
like this
6*-3=-18
-18*-3=54
ans is 54 -18 6
4) [6 3 3 9] [12 5 7 35] [8 6 2 ?]
2nd +3rd =1st
2nd *3rd =4th
so ans is 12
5) 7 -14 -4 15 -30 -20 -21 42 ?
1st *-2=2nd
2nd + 10=3rd
like this
7*-2=-14
-14+10=-4
ans is 42+10=52
6)7 4 6 3 4.5 1.5 2.25 -0.75
see 1 3 5 7 9 term
7-1=6
6-1.5=4.5
4.5-2.25=2.25
2.25-1.25=1
so ans is 1
because diff is 1 1.5 2.25 so next is 1.25
7) [7 0 1 8] [5 12 9 26] [3 23 2 28]
see 1st term of each group is
7 5 3 so next is 1
ans 1
8) 13 21 32 49 78 132
21-13= 8
32-21=11----> 11-8=3
49-32=17----> 17-11=6
78-49=29----> 29-17=12
131-78=53---> 53-29=24
then (24*2)=48+53=101 and 131+101= 232

15-16=-1
ans =-1
12)[13 24 36] [ 23 34 56] [33 44 96] [43 54 ?]
1st term each group is +10 of previous
2nd is +10 of previous
3rd is like 20 40 60
so ans is 156
