What will next in the series : 7,26,63, 124 .... Solution : this is a series based on logic here we can see a pattern : 2^3 -1 = 7, 3^3 -1 = 26, 4^3 -1 = 63, 5^3 -1 = 124 .... so the next digit is 6^3 -1 = 216 -1 = 215 answer

31.
What will come next in this series : 9, 28, 65, 126 ... Solution : this is a series based on logic here we can see a pattern : 2^3+1 = 9, 3^3 +1 = 28 , 4^3+1 = 65, 5^3+1 = 126 .... so the next digit is 6^3 +1 = 216 +1 = 217 answer

What will come in the following series : 7,11,13,23,25,47 ... Here we can see two series : 7 , 13, 25 ... and 11,23,47 ... 7*2 -1 = 13, 13*2 -1 = 25 ... so next digit should be 25*2 -1 = 49 answer

33.
What will come next in the series : 0,15,80, ..... Here we can notice following pattern : 1^4 -1 = 0 2^4 -1 = 15 3^4 -1 = 80 so next digit should be 4^4 -1 = 255 answer

34.
What will come next in the series : 1, 9, 29, 67 .... Here the series is : 1^3 + 0 2^3 +1 3^3 +2 so next item should be 5^3 +4 =129 answer
