Question

If a, b, c, d, e are five consecutive odd numbers. their average is

Options:

A . 5(a + 4)

B . `(abcde)/(5)`

C . 5(a + b + c + d + e)

D . None of these

Answer: Option D

Clearly, b = a + 2, c = a + 4, d = a + 6 and e = a + 8.

`:.` Average = `(a + (a + 2) + (a + 4) + (a + 6) + (a + 8) )/(5)` = `((5a + 20)/(5))`= (a + 4)
