Analyzing the Code Language Pattern

The problem provides examples of words coded into numbers in a specific language. We are given that 'IT' is coded as '58' and 'SAD' is coded as '48'. We need to find the code for 'FISH' using the same pattern.

Let's look at the alphabetical positions of the letters in the given words:

• I is the 9th letter.
• T is the 20th letter.
• S is the 19th letter.
• A is the 1st letter.
• D is the 4th letter.

Decoding 'IT' and 'SAD'

For 'IT', the sum of the alphabetical positions is $\text{9} + \text{20} = \text{29}$. The coded value is 58. We observe that $\text{29} \times \text{2} = \text{58}$.

For 'SAD', the sum of the alphabetical positions is $\text{19} + \text{1} + \text{4} = \text{24}$. The coded value is 48. We observe that $\text{24} \times \text{2} = \text{48}$.

It appears the pattern is to sum the alphabetical positions of the letters in the word and then multiply the sum by 2.

Coding 'FISH'

Now, let's apply this pattern to the word 'FISH'. First, find the alphabetical positions of the letters in 'FISH':

• F is the 6th letter.
• I is the 9th letter.
• S is the 19th letter.
• H is the 8th letter.

Next, sum the alphabetical positions of the letters in 'FISH':

Sum = $\text{6} + \text{9} + \text{19} + \text{8} = \text{42}$

Finally, multiply the sum by 2 to get the code for 'FISH':

Code for FISH = $\text{42} \times \text{2} = \text{84}$

Conclusion

Following the established pattern from the examples 'IT' and 'SAD', the code for 'FISH' is calculated to be 84.
