Show answer & explanation
Correct answer: B
Pattern: in each sector, add the two outer numbers and multiply the sum by the previous integer.
Top-right sector:
14 + 7 = 21, and21 x 20 = 420.Bottom-right sector:
9 + 11 = 20, and20 x 19 = 380.Bottom-left sector:
15 + 3 = 18, and18 x 17 = 306.
For the missing sector, the inner number is 552. Since 24 x 23 = 552, the two outer numbers must add to 24.
One outer number is 6, so the missing number is 24 - 6 = 18.
