THE LOGIC FOLLOWED HERE IS:

ALPHABETS AT ODD PLACES ARE INCREASED  TO 2 POSITIONAL VALUES

ALPHABETS AT EVEN PLACES ARE DECREASED  TO 2 POSITIONAL VALUES

D → (+2) → F

E → (-2) → C

T → (+2) → V

E → (-2) → C

C → (+2) → E

T → (-2) → R

AND

H → (+2) → J

E → (-2) → C

I → (+2) → K

G → (-2) → E

H → (+2) → J

T → (-2) → R

SIMILARLY

M → (+2) → O

O → (-2) → M

T → (+2) → V
