Conditions:
i If the first element is a symbol and the last element a number, the codes for these two (the first and the last elements) are to be interchanged.
ii If the first element is an odd number and the last element an even number, the first and last elements are to be coded as ©.
iii If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
What will be the code for the following group?
^ 5 2 & 4

Conditions:
i If the first element is a symbol and the last element a number, the codes for these two (the first and the last elements) are to be interchanged. ​→(Follow) interchange codes.
ii If the first element is an odd number and the last element an even number, the first and last elements are to be coded as ©. → Does not apply.
iii If both second and third elements are perfect squares, the third element is to be coded as the code for the second element. → Does not apply.​
^ 5 2 & 4

Direct codes:
^ → E
5 → H
2 → T
& → F
4 → A

After swapping first and last codes:
First → A
Second → H
Third → T
Fourth → F
Last → E

Final code = AHTFE
