- Ans is : 85
4 |20|35|49|62|74
Difference between 4 to 20=16 then 15|14|13|12|11
74+11=85 - 10 years agoHelpfull: Yes(23) No(1)
- d.85
16,15,14,13,12,11
these difference are get addded in the next term - 10 years agoHelpfull: Yes(3) No(1)
- ANS 85
DIFF IS 15 14 13 12 11
SO 74+11 - 10 years agoHelpfull: Yes(0) No(1)
- ans:85
20-4=16
35-20=15
49-35=14

85-74=11 - 10 years agoHelpfull: Yes(0) No(0)
- 20-4 = 16 ; 35 - 20 = 15 ; 49 -35 =14 ; 62 - 49 = 13 ; 74 - 62 = 12 ;
16 ; 15 ; 14 ; 13 ; 12 ; 11
74 +11= 85 Ans - 10 years agoHelpfull: Yes(0) No(0)
- 4+16=20, 20+15=35, 35+14=49, 49+13= 62, 62+12=74, 74+11=85
- 9 years agoHelpfull: Yes(0) No(0)
- difference between 4&20=16
then 15..14..13..12..
so 74+11=85
d.85 - 9 years agoHelpfull: Yes(0) No(0)
- 11.
coz all the numbers are increased by the difference between consecutive numbers - 7 years agoHelpfull: Yes(0) No(0)
- 4:20:35:49:62:74:?
ans=85
because difference between 4-20=16,then 20:35=15,,,,like that 14,13 and 12
so finally 11 will be the diff between 74:? so answer is 85 - 6 years agoHelpfull: Yes(0) No(0)
- 4, 20, 35, 49, 62, 74, 85
+16, +15, +14, +13, +12, +11 - 6 years agoHelpfull: Yes(0) No(0)
TCS Other Question
A permutation is often represented by the cycles it has, For example, if we permute the numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the (132) says that the first number has gone to the position 3, the third number has gone to the position 2, and the second number has gone to the position 1, and (5 4) means that the fifth has gone to position 4 and fourth has gone to position 5. The numbers with brackets are to be read cyclically. If a number has not changed position, it is kept as a single cycle. This 5 2 1 3 4 is represented as (1345)(2). We may apply permutations on itself if we apply the permutation (132)(54) once, we get 2 3 1 5 4. If we consider the permutation of 7 numbers (1457)(263) what is its order ( how many times must it be applied before the numbers appear in the original order) ?
a. 12
