Question

The average of 5 consecutive even numbers A,B,C,D,E is 34 .what is the product of B and E.

Answer 1

Step-by-step explanation:

$\frac{a + b + c + d + e}{5} = 34 \\ = > \frac{ a + (a + 2) + (a + 4) + (a + 6) + (a + 8)}{5} = 34 \\ = > \frac{5a + 20}{5} = 34 \\ = > \frac{5(a + 4)}{5} = 34 \\ = > a + 4 = 34 \\ = > a = 34 - 4 = 30 \\ \\ a = 30 \\ b = 30 + 2 = 32 \\ c = 30 + 4 = 34 \\ d = 30 + 6 = 36 \\ e = 30 + 8 = 38 \\ \\ b \times e = 32 \times 38 = 1216$
