1. Letters = -2 in alphabet order Z-X-V-T-R-P-N
2. Numbers = order number * (+1)
   2-6-12-20-30-42-56
   1*2-2*3-3*4-4*5-5*6-6*7-7*8
   N66

Answer 2

The answer is N56
The letters of the alphabet follow the sequence Z, X, V, T,R, p and next is N
The numbers follow the sequence: 2 + 4 = 6,, 6 +6 = 12, 12 + 8 = 20, 20 +10 = 30 , 30 + 12 = 42 , then 42 +14 = 56
