What is the next number of the following sequence
673, 697, 10117, 125422, 878842,.........

OPtion

1) 897723432
2) 4567583
3) 23489763
4) 12854980
5) 980932452

7) 991657899
8) 987043526
9) 5678437
10)None of these

Solution

673 is converted as (6+1)|(7+2)|(3+3), on reversing we get 697,
697 is converted as (6+1)|(9+2)|(7+3), on reversing we get 10117,
10117 is converted as (1+1)|(0+2)|(1+3)|(1+4)|(7+5), on reversing we get 125422

673, 697, 10117, 125422, 878842,.........
673...697
add 1 to 6 to get 7.
add 2 to 7 to get 9.
add 3 to 3 to get 6.
place numbers in reverse order to get 697.
similarly 697... 10117
..

so for next number from 878842..
add 1 to 8 to get 9.
add 2 to 7 to get 9.
add 3 to 8 to get 11.
add 4 to 8 to get 12.
add 5 to 4 to get 9.
add 6 to 2 to get 8.
so next number will be 89121199.... option 6

(673, 697, 10117), (125422, 878842,x)
Divide the series into 2 group...

3rd no. = (2nd no.) + (Reverse of diff. of 1st nd 2nd calculated digit-by-digit)

1) Diff. between 673 nd 697
6-6=(0)... 9-7=(2)...7-3=(4)... (ie diff. is 024)
3rd no. = 693+Reverse of (024) => 697+420
=> 6+4=(10)... 9+2=(11)...7+0=(7) = 10117

Similarly for 2nd group
2) Diff. between 125422 nd 878842 is
8-1=(7)...7-2=(5)...8-5=(3)...8-4=(4)...4-2=(2)...2-2=(0)...
Diff is 753420

So x = 878842 + Rev(753420)
=> 878842 + 024357
8+0=(8)... 7+2=(9)... 8+4=(12)... 8+3=(11)...4+5=(9)... 2+7=(9)
x = 89121199

Ans : 89121199 (Option 6)

next number of the following sequence
673, 697, 10117, 125422, 878842,......... 89121199
673....(6+1..7+2..3+3)..... (7 9 6)..>> 697

878842... 9-9-11-12-9-8 .... 89121199

Karan   10 years AGO

add 1 in 1st digit, 2 in 2nd digit, .....
now put all the new numbers in reverse order to get next number.
From 878842
8+1=9
7+2=9
..
..
2+6=8
so next number = 89121199

673=(6+1)(7+2)(3+3) = 796 rev = 697

878842=(8+1)(7+2)(8+3)(8+4)(4+5)(2+6)= 9 9 11 12 9 8 rev
89121199

Take the First 3 as the group,
6 7 3
+0 +2 +4
6 9 7
+4 +2 +0
10 11 7
And now for the next number,
1 2 5 4 2 2
+7 +5 +3 +4 +2 +0
8 7 8 8 4 2
+0 +2 +4 +3 +5 +7
8 9 12 11 9 9

It is coded as follows
673 is coded as (6+1)(7+2)(3+3)=796 on reversing we get 697
Similarly intermediate nos are coded
Now 878842 is coded as(8+1)(7+2)(8+3)(8+4)(4+5)
(2+6)=99111298 on reversing we get 89121199
