Detailed Explanation & Answer
3 × 4 = 12
12 × 3 = 36
36 × 4 = 144
144 × 3 = 432
432 × 4 = 1728 ← This should be the correct term, not 1738
1728 × 3 = 5184

So, the correct pattern is:
×4, ×3, ×4, ×3, ×4, ×3...

1738 breaks this pattern — it should be 1728.
3 × 4 = 12
12 × 3 = 36
36 × 4 = 144
144 × 3 = 432
432 × 4 = 1728 ← यह सही पद होना चाहिए, 1738 नहीं
1728 × 3 = 5184

तो, सही पैटर्न है:
×4, ×3, ×4, ×3, ×4, ×3...

1738 इस पैटर्न को तोड़ता है — इसे 1728 होना चाहिए।
