Can you please help me with this RSA Question?

Decipher the following message to get the initials of an organization: 88 17 2 Each letter is encoded using the same 0-25 scheme as the previous problem, then individually encrypted in RSA with public key (e = 23, n = 55). For example, the message "HEY" wll be encoded and encrypted as follows. The letter H corresponds to 7, and 723 mod 55 equals 13. The letter E corresponds to 4, and 423 mod 55 equals 9. The letter Y corresponds to 24, and 2423 mod 55 equals 19. So the mssage "HEY", when encoded and encrypted, reads as follows. 13 9 19 Solve for the private key d, then decrypt and decode the "8 8 17 2" message. What inials do you find
