In the two numerical sequences below,one number that appears in the top sequence should appear in the bottom sequence and vice versa. Which two numbers should be changed round?

2, 5, 11, 15, 47
3, 7, 23, 31, 63

Answer

2,   5,   11,      15,      47
  +3   +6    +4     +32         3 , 6 , 4 , 32 ...... No pattern there it seems.

Let's try the second series.
3,    7,      23,    31,      63
    +4     +16     +8     +32    4,16 , 8, 32 ,........ If we change the order of 16 and 8 here it would be
4,8 ,16, 32 ,........

So the series would be  3,    7,   15,   31,  63, .........
 
If we replace 15 by 23 in the first series,

2,     5,     11,       23,      47
    +3   +6      +12       +24           There is also a pattern now.



The numbers to be changed round 15 and 23

The top set of six numbers has a relationship to the set of six numbers below. The two sets of six boxes on the left have the same relationship as the two sets of six boxes on the right. Which set of numbers should therefore replace the question marks?

14  27  56   18   76  32    ||  68  64  71 19  25  49
5    9   11    9   13   5     ||   ?    ?    ?   ?   ?    ?

Answer

14  27  56   18   76  32    ||  68  64  71 19  25  49
5    9   11    9   13   5     ||   ?    ?    ?   ?   ?    ?

1+4 =5   1+8=9

2+7=9    7+6=13

5+6=11   3+2=5

6+8=14    6+4=10     7+1=8     1+9=10   2+5=7   4+9=13


14  27  56   18   76  32    ||  68  64    71   19    25  49
5    9   11    9   13   5     ||   14  10    8    10     7   13

Find out the missing number.

5, 16, 49, ? , 445 , ..................

Answer

Tn = (Tn-1 * 3) +1

16 =(5*3) +1

49= (16*3) +1

? = (49*3) +1 = 148

445= (138 *3) +1

Missing number = 148

7382961 is to  2016

and  3864987  is to 2124

therefore 7958279 is to ?

Answer

7382961     7+3+8 +2=20    9+6+1=16

3864987     3+8 +6+4 =21   9+8+7=24

7958279     7+9+5+8=29    2+7+9=18 

Missing number =2918


Some one at office gave another excellent answer.

"2225  I think

The sum of the individual numbers in 7382961 is 36   1st and 3rd numbers in 2016 added is 3. 4th number plus 2nd number is 6  ie 36
The sum of the individual numbers in 3864987 is 45   1st and 3rd numbers in 2124 added is 4. 4th number plus 2nd number is 5  ie 45
The sum of the individual numbers in 7958279 is 47   1st and third number in 2225 added is 4  4th number plus 2nd number is 7  ie 47  "

But that method does not give one specific answer.

Answer
 
Change the order of the digits

12593   ----- >  35291

29684  ------->  46982

72936 -------->  69237
