If EAGLE is coded as FZHKF, what is the code for THANKS?

Explanation: The coding rule alternates adding 1 and subtracting 1 to consecutive letters, starting with +1 on the first letter.

• Example for EAGLE:

• E → F (+1)

• A → Z (−1)

• G → H (+1)

• L → K (−1)

• E → F (+1)

Apply the same pattern to THANKS:

• T → U (+1)

• H → G (−1)

• A → B (+1)

• N → M (−1)

• K → L (+1)

• S → R (−1)

Resulting code: UGBMLR
