Decoded as:
plainText
1 Think step by step
Decoding Method:
1.Pair the letters in the ciphertext.
2.Convert each letter to its numerical position in the alphabet (A=1, B=2, …, Z=26).
3.Sum the numerical values of each pair.
4.Compute the average of the sum (divide by 2).
5.Convert the average back to a letter (1=A, 2=B, …, 26=Z).
Apply this method to the given ciphertext:
plainText
1 oyekaijzdf aaptcg suaokybhai ouow aqht
mynznvaatzacdfoulxxz
