Task: Find two pairs of bits that can be joined to form words with opposite meanings.

Step 1: Join possible bit pairs to form real words

• EXP + AND = EXPAND
• RED + UCE = REDUCE

Step 2: Identify opposite meanings

EXPAND means to enlarge or increase.
REDUCE means to shrink or decrease.

Hence, these are antonyms.

✅ Final Answer:

• Pair 1: (5) EXP + (7) AND → EXPAND
• Pair 2: (9) RED + (2)

Sequence Pattern Problem

Given the sequence: HEC, JGE, LIG, NKI, ______

Step 1: Analyze the first letters:

• H (8), J (10), L (12), N (14)
• Pattern: +2 each time

Step 2: Analyze the second letters:

• E (5), G (7), I (9), K (11)
• Pattern: +2 each time

Step 3: Analyze the third letters:

• C (3), E (5), G (7), I (9)
• Pattern: +2 each time

Step 4: Find the next letters by adding 2:

• First letter: N (14) + 2 = P (16)
• Second letter: K (11) + 2 = M (13)
• Third letter: I (9) + 2 = K (11)
