1) .7 , 1.2, 1.2 , 2.2 , 1.7, 3.2, 2.2, 4.2 , ?
.7+.5=1.2+.5=1.7 ans 2.7
2) 81, 9^2, 162, 49, 7^2, 98, 25, 5^2, 50, 64, 8^2 ?
81*2=162 so,ans = 64*2= 128
3) 1, 1, 2, 4 , 6, 36, 39, 1521, ?
1+1=2
4+2=6
36+3=39
1521+4= 1525 (ans)
4) 2, 3, 10, 15, 26, 35,50, ?
5) 2, 8, 3, 27, 4, 64, 5, 125, 6, 216, ?
See alternate no.s -> 2, 3, 4.ans=7
6) 2, 3, 6, 13, 28, ?
*2-1, *2+0, *2+1.ans= 28*2+3= 59
7) 38, 36, 76, 35, 114, 34, ?
Alternate -> 38+38=76
76+38=114
114+38=152 (ans)
8) 1/5, 1/2, 1/3, 2/5 , 1, 2/3,3/5, 3/2, 1, 4/5, ?
Alternate starting wi
th 1/2 ; skip 2 and ï½½ -> 1/2, 1, 3/2 , 2 (ans =2)
9) 96, 64, 128, 192, 128, 256, 288, 192, ?
Break such questions like this (96, 64, 128,) (192, 128, 256,) (288, 192, ?)
First*2=second set\'s numbers. First*3= third set. Ans=128*3
10) 1370, 1320, 1070, -180, ?
difference -> -50, -250, -1250 -> 50*5, 250*5, next will be -1250*5
11) 3, 2, 1, 4, 5, 4, 5, 1, 0, 6, 3, 2, ?
3,( 2, 1), 4,( 5, 4), 5, (1, 0), 6, (3, ?) second term one less . so ans = 2
12) 1 1 1 2 2 2 3 4 3 3 5 6 ?
(1 1) 1 2 (2 2) 3 4 (3 3) 5 6 ? ans=4
13) 507, 169, 248, 62, 36, 12, 168, 42, 168 ?
(507= 169*3), 248, 62, (36=12*3), 168, 42, (168=x*3)-> x=56 (ans)
14) 7.2, 2.2, 3.2, 16, 11, 12, 60, 55, 56, ?
7.2 + 8.8= 16+ 44= 60 + 2.2= 62.2 (ans) [not sure abt answer]
15) 2, 6, 5, 14, 11, 26, 17 , ?
Alternate starting with first: +3 , +6 , +6
Now starting with second number: +8, +12 , +12 . so ans = 26+12
16) 115, 100, 86, 74, 65, 60, ?
Difference : 15, 14, 12,9, 5 Now difference of these : 1, 2, 3, 4, next 5
So 5-5=0
Ans=60-0=60
17) 8 5 9 7 2 25 5 1 16 8 6 ?
(8 -5=3 ) -> 3^2=9 (7-2=5)->5^2= 25 5 1 16 (8- 6=2) so answer 2^2=4
18) -5 1 -11 23 29 17 -20 -14 ?
-5 (1 -12=-11) 23 (29 -12=17) -20 (-14 -12=-26) ans=-26
