ANN. If you give each letter a number according to its position in the alphabet:
TED = 20 + 5 + 4 = 29
ANN = 1 + 14 + 14 = 29(George and Mary each add to 57)

ANN. If you give each letter a number according to its position in the alphabet:
TED = 20 + 5 + 4 = 29
ANN = 1 + 14 + 14 = 29

What is the missing number?

2 3 4 15 12
3 4 5 28 20
4 5 6 45 30
5 6 7 66 42
6 7 8 ?? 56

Show the answer »

91. To get the number in the fourth column, you add the numbers in column 1 and 2, then multiply by the number in column 2. f(n,m) = (n + m) * m
For example, f(2,3) = (2 + 3) * 3 = 15. Thus f(6,7) = (6 + 7) * 7 = 91
