Question

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

Options

  • 5(a + 4)

  • `(abcde)/5`

  • 5(a + b + c + d + e)

  • None of these

MCQ

Solution

None of these

Explanation:

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)
