Answer 1

The pattern followed here is:

Logic: First number × 10 = Second number & Second number × 20 = Third number.

Let's check each option one by one:

Option 1) (6 – 60 – 1200)

⇒ 6 × 10 = 60 & 60 × 20 = 1200 (Correct)

Option 2) (7 – 70 – 1600)

⇒ 7 × 10 = 70 & 70 × 20 = 1400 ≠ 1600 (Incorrect)

Option 3) (5 – 50 – 1000)

⇒ 5 × 10 = 50 & 50 × 20 = 1000 (Correct)

Option 4) (4 – 40 – 800)

⇒ 4 × 10 = 40 & 40 × 20 = 800 (Correct)

Hence, the correct answer is "(7 – 70 – 1600)".
