Read Solution (Total 12)
-
- 1/2+1/16=9/16
9/16+1/16==5/8
5/8+1/16=11/16
so ans is 11/16........................... - 9 years agoHelpfull: Yes(73) No(1)
- 1/2=8/16
next 9/16
5/8=10/16
so next 11/16 - 8 years agoHelpfull: Yes(11) No(0)
- solution = 49/256 as
(1/2)^1 = 1/2
(3/4)^2 = 9/16
(5/8)^1 = 5/8
(7/16)^2 = 49/256
(9/32)^1 = 9/32
.....
The numerator are odd numbers (1,3,5,7,...) and
the denominator are power of 2 (2,4,8,16,..) - 8 years agoHelpfull: Yes(3) No(2)
- 1/2+1/16=9/16
1/2+1/8=5/8
1/2+1/4=3/4
ans 3/4 - 9 years agoHelpfull: Yes(2) No(12)
- It's a simple addition series
9/16 - 1/2 = 1/16
5/8 - 9/16 = 1/16
and
5/8 + 1/16 = 11/16
so the next term is 11/16 - 8 years agoHelpfull: Yes(1) No(0)
- 9/16-1/2=1/16
5/8-9/16=1/16
So, 5/8+1/16=11/16
i.e now if we cross check
11/16-5/8=1/16 - 8 years agoHelpfull: Yes(1) No(0)
- 49/256

- 1/2*9/8,
9/16*10/9,
5/8*11/10=11/16
- 9 years agoHelpfull: Yes(0) No(1)
- 1/2, (3/4)^2,5/6,(7/8)^2 = 49/84 answer .

- 1/2,9/16,5/8
(i). 1/2-9/16= -1/16
(ii). 9/16-5/8= -1/16
so the difference is -1/16
now,
(iii). 5/8-x= -1/16
therefore x= 19/24 (Answer) - 8 years agoHelpfull: Yes(0) No(0)
- the terms are actually in the form of 8/16,9/16,10/16... therefore next term will be 11/16
- 8 years agoHelpfull: Yes(0) No(0)
- 11/16
8/16, 9/16, 10/16, 11/16 - 6 years agoHelpfull: Yes(0) No(0)
