So, the required number is -128.
2, 6, 12, 20, 30, 42, 56, ?
848 05ff44c7ffc463f4c73681a68The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
So, the next number is 8 x 9 = 72.
8, 7, 11, 12, 14, 17, 17, 22, ?
612 05ff44bcdfc463f4c73681695Explanation:
There are two series (8, 11, 14, 17, 20) and (7, 12, 17, 22) increasing by 3 and 5 respectively.
5, 16, 49, 104, ?
645 05ff44b1bfc463f4c73681386Explanation:
+11 =16
+33 =49
+55 =104
+77 =181
6, 14, 36, 98, ?
1201 05ff44a5f1c485c5622a34706Explanation:
6 = 1^1 + 2^1 + 3^1
14 = 1^2 + 2^2 + 3^2
36 = 1^3 + 2^3 + 3^3
98 = 1^4 + 2^4 + 3^4
Thus the next number will be
1^5 + 2^5 + 3^5 = 276
2, 12, 36, 80, 150, ?
825 05ff449ea1c485c5622a34602Explanation:
A unique pattern has been made into use in this series.
All numbers are (n^3 + n^2) where n is 1, 2, 3 and so on.
