Question

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

Options:

A . a+4

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

C . ${abcde}/5$

D . 5(a+4)

Answer: Option A
Answer: (a)
b = a + 2
c = b + 2 = a + 4
d = c + 2 = a + 6
e = d + 2 = a + 8
∴ Required average
= ${a+a+2+a+4+a+6+a+8}/5$
= ${5a+20}/5$ = a+4
