Observe the following table and determine the missing number in the last cell:A B C D Result 5 2 3 10 40 4 3 5 8 40 6 4 2 12 ?
48
Look for a single rule that links the four values A, B, C, D to the Result in every row.
Row 1: \(5+2+3+10 = 20\) and \(20 \times 2 = 40\).
Row 2: \(4+3+5+8 = 20\) and \(20 \times 2 = 40\).
Both rows confirm the rule: add the four numbers, then double the sum.
Row 3: \(6+4+2+12 = 24\).
Doubling gives \(24 \times 2 = 48\).
The rule 'sum of the four entries times two' fits every row consistently.
The missing number is 48.
