Answer 2

Answer:  The next number is 169

Step-by-step explanation:

19 , 25 , 42 , 71 , 113 , ?

So first we have to calculate the difference between each numbers

25 - 19 = 6

42 - 25 = 17      

71 - 42 = 29

113 - 71 = 42

? - 113 ….(1)

  now calculate next difference between  6,  17 , 29 , 42 , ?

17 - 6 = 11

29 - 17 = 12

42 - 29 = 13

? - 42 = 14

Here we can understand that the next difference is  14

so  42 + 14 = 56

 → 6,  17 , 29 , 42 , 56

now put the value 56 in eq. (1)

113 + 56 = 169
