Answer 2

Answer:

1) 82, 78, 79

82 -2^2 = 78

78 + 1^2= 79

79 - 0^2 = 79

So next number is 79

2) 1/2 5/6 7/6 3/2

1/2 = 3/6

5/6 =5/6

7/6=7/6

3/2 =9/6

Here numerator is increasing by 2

So the next number is 11/6

3) 25, 50, 51, 102,

25 x2 = 50

50+1 = 51

51x 2 = 102

102 +1 = 103

So next number is 103

4) 13, 39,117,351

13x3=39

39x3=117

117x3=352

351 x3=1053

So the next number is 1053

5) 2/3 1/3 1/6 1/12

2/3 x 1/2=1/3

1/3x 1/2=1/6

1/6 x 1/2=1/12

1/12 x 1/2=1/24

So the next number is 1/24
