N to O: +1 (N, O)
O to P: +1 (O, P)
P to Q: +1 (P, Q)
Second position:
G to I: +2 (G, H, I)
I to K: +2 (I, J, K)
K to M: +2 (K, L, M)
M to O: +2 (M, N, O)
Third position:
B to E: +3 (B, C, D, E)
E to H: +3 (E, F, G, H)
H to K: +3 (H, I, J, K)
K to N: +3 (K, L, M, N)
Following the identified pattern:
The first position follows the pattern of increasing by 1.
The second position follows the pattern of increasing by 2.
The third position follows the pattern of increasing by 3.
