Answer

25,     30 ,    39 ,   52 ,   69, _ ,.........

     +5     +9     +13    +17      Next number   +21

Next number in the series  69 + 21 = 90 

25, 30 , 39 , 52 , 69, 90  ,.........

Pattern Recognition - 254

Find out the next number in the series.
39 ,126 , 2725 ,522 ,_,.............

Answer

39 ,           126   ,               2725 ,                        522 , _ ,.............

39 ,     3+9 diff(3,9)      1+26 diff(1,26)        27+25 diff(27,25)

Next number 5+22  diff(5,22) = 2717

39 ,126 , 2725 ,522 ,2717 ,.............

Pattern Recognition - 253

Find out the next number in the series.
4, 6 , 9 , 13 , 11 , 8 , 4 , 6,_ ,..............

Answer

4,     6 ,     9 ,      13 ,    11 ,    8 ,    4 ,       6,_ ,..............

   +2     +3      +4       -2      -3      -4     +2

Next number  6 + 3 = 9

4, 6 , 9 , 13 , 11 , 8 , 4 , 6, 9,..............

Pattern Recognition - 252

Find out the next number in the series.

1568 , 1482 , 1454 , _ ,..............

Answer 

1568 , 1482 , 1454 , _ ,..............

1568 - Reverse(68) = 1568 - 86 = 1482 

1482 - Reverse(82) = 1482 - 28 = 1454

Next number   1454 - Reverse(54) = 1409

1568 , 1482 , 1454 , 1409,..............
