We know that alphabet A=1, B=2, C=3, D=4 ........ Z=26

Given that SCIENCE is written as 7-5-16-7-11-5-21

 we represent in the form of alphabet position 

S C I E N C E

19 3 9 5 14 3 5

the  pattern is followed from Right side to left side add +2 alphabet position  

(5+2) (3+2) (14+2) (5+2) (9+2) (3+2) (19+2)

  7 - 5 - 16 - 7 - 11 - 5 - 21 

Similarly, MUSEUM be written in that code language

MUSEUM
