Understanding the Coding Pattern

The question asks us to determine the coding pattern used to transform the word TEACHER into TEACREH and then apply this pattern to code the word FRIENDS.

Analyzing the TEACHER Transformation

Let's break down the original word and the coded word:

• Original Word: T E A C H E R
• Coded Word: T E A C R E H

By comparing the two, we can observe the following changes:

• The first four letters (T, E, A, C) remain in their original positions.
• The last three letters (H, E, R) appear to be rearranged.

Specifically, the sequence H E R seems to have been reversed to become R E H.

Let's verify this: The last three letters of TEACHER are H, E, R. Reversing this sequence gives R, E, H.

So, the pattern is: Keep the first four letters as they are, and reverse the order of the last three letters.

Applying the Pattern to FRIENDS

Now, we apply the same identified pattern to the word FRIENDS.

The word is: F R I E N D S

Following the pattern:

1. Keep the first four letters unchanged: F R I E
2. Identify the last three letters: N D S
3. Reverse the order of these last three letters: S D N

Combine the unchanged first part with the reversed last part:

F R I E + S D N = FRIESDN

Matching with Options

Let's compare our result with the given options:

• Option 1: FRESIND - Incorrect
• Option 2: FIRNEDS - Incorrect
• Option 3: FRIESND - Incorrect
• Option 4: FRIESDN - Correct

The coded word for FRIENDS, following the pattern derived from TEACHER, is FRIESDN, which matches Option 4.
