If A=2 and D=5, and SEA=28, then COUNTRY=______

The coding scheme assigns each letter a value equal to its positional value in the English alphabetical order plus 1.
A=1+1=2

D=4+1=5

Let us check for the word SEA:

S=19+1=20

E=5+1=6

A=1+1=2

Sum=20+6+2=28
Now, calculating the value for COUNTRY:

C=3+1=4

O=15+1=16

U=21+1=22

N=14+1=15

T=20+1=21

R=18+1=19

Y=25+1=26

Total Sum=4+16+22+15+21+19+26=123
