- 8 years agoHelpfull: Yes(15) No(0)
- 1+3+1=5
5/2=2.5
5+1+4=10
10/2=5
4+8+7=19
19/2=9.5

- 1) 1,3,1,2.5,5,1,4,5,4,8,7,?
ans: 9.5
sol:-take first 4 number
1,3,1,2.5
1+3+1=5, 5/2= 2.5
next 4 number is : 5,1,4,5
5+1+4=10, 10/2=5
next number is: 4,8,7,?
4+8+7=19, 19/2=9.5
2) 1,1,3,2,1,5,3,4,10,4,2,?
ans : 12
sol : there are 3 different series
a) 1,2,3,4
b) 1,1,4,2
c) 3,5,10,?
3+2=5
5*2=10
10+2=12
3) 5,5,7,7,9,11,11,13,13,17,15,19,17,?
ans : 23
sol : divide it into 2 different series
a) 5,7,9,11,13,15,17
5+2=7 7+2=9
9+2=11 11+2=13
13+2=15 15+2=17
b) 5,7,11,13,17,19,?
5-7= -2 7-11= -4
11-13= -2 13-17 = -4
17-19= -2 19+4 =23 - 7 years agoHelpfull: Yes(2) No(1)
- 2) (1+1+3)/2=2.5-0.5=2
(1+5+3)/2=4.5-0.5=4
(10+4+2)/2=8-0.5=7.5 - 8 years agoHelpfull: Yes(1) No(2)
- 1,1,3,2,1,5,3,4,10,4,2
There are 3 series
1,2,3,4
1,1,4,2
3,5,10,?
Now 3+2=5
5*2=10
10+2=12 Ans - 7 years agoHelpfull: Yes(1) No(2)
- 2) 1*1+3=4/2=2
1*5+3=8/2=4
10*4+2=42/2=21
ans= 21 - 7 years agoHelpfull: Yes(1) No(0)

13+4=17
17+2=19
19+4=23
so the answer is 23 - 8 years agoHelpfull: Yes(0) No(0)
