The next number is 1595.
The series is obtained by multiplying the previous number by 4 and then subtracting (n - 1).
1st number = 2 - ( 1 - 1) = 2
2nd number = (4 x 2) - (2 - 1) = 7
3rd number = (4 x 7) - (3 - 1) = 26
4th number = (4 x 26) - (4 - 1) = 101
5th number = (4 x 101) - (5 - 1) = 400
6th number = (4 x 400) - (6 - 1) = 1595
