A, B, C, D are four consecutive odd integers and their average is 42. What is the product of B and D?

Correct answer:

p =  1845

Step-by-step explanation:

m=42 m = 4A+B+C+D B=2+A C=2+B D=2+C  4 m=A+(2+A)+(4+A)+(6+A) 4 42=A+(2+A)+(4+A)+(6+A)  4A=156  A=4156=39  A=39  B=2+A=2+39=41 C=2+B=2+41=43 D=2+C=2+43=45  p=B D=41 45=1845
