Q. What is the next number of the following sequence
32, 29, 26, 64, 61, 58, 96, 93, 93, ...
Read Solution (Total 6)
-
- 32,29,26,64,61,58,96,93,93
(32,29,26),(64,61,58),(96,93,93),(x,x-3,x-6)
32-3=29,29-3=26
64-3=61,61-3=58
96-3=93,93-3=60
take 1st term of each group
32,64,96,x
32*1=32
32*2=64
32*3=96
32*4=x => 128
next three numbers= (x,x-3,x-6)= (128,125,122) - 10 years agoHelpfull: Yes(28) No(2)
- There is a misprint in the series. It should be:
32, 29,26, 64,61,58, 96,93,90, ?,?,?
now,
[32,29,26], [64,61,58], [96,93,90]
the series is [32, 32-3, 32-6], [32*2=64, 64-3, 64-6], [32*3=96, 96-3, 96-6]
next will be: [32*4=128, 128-3,128-6]
so, 128,125,123... - 10 years agoHelpfull: Yes(11) No(0)
- 128
32*2=64, 32*3=96, 32*4=128 - 10 years agoHelpfull: Yes(0) No(0)
- 128 32+29=61; 32+26=58;so on 32+96=128
- 10 years agoHelpfull: Yes(0) No(0)
- ans is 87
32,26,61,96,93 one series
29,64,58,93,? other series
64-29=35
64-58=6
93-58=35
93-87=6 - 10 years agoHelpfull: Yes(0) No(0)
- ans is 96+32=128 and the last 93 should be 90
- 10 years agoHelpfull: Yes(0) No(0)
