Average Practice Test 7

Let the four consecutive odd numbers A, B, C and D are represented as x, x + 2, x + 4 and x + 6 respectively.
$\frac{\mathit{x}+\mathit{x}+2+\mathit{x}+4+\mathit{x}+6}{4}=54$
$4\mathit{x}+12=216$
$\mathit{x}=51$
The four numbers are 51, 53, 55, 57
Product of A and C = 51 × 55 = 2,805
