Number reasoning 1.26.9.124. ().342
1.26.9.124.( 65 ).342
This problem examines the cubic number correction
Original sequence 0, 27, 8, 125, 64, 343
They are 0, 3, 2, 5, 4 and 7
Do difference 3, - 1,3, - 1,3 for the cyclic sequence
So now the sequence is
0^3+1=1
3^3-1=26
2^3+1=9
5^3-1=124
4^3+1=65
7^3-1=242
