Question

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

Answer 1

Answer:

Step-by-step explanation:

(a+b+c+d+e)/5

Answer 2

Answer:

Step-by-step explanation:

→ Since they are consecutive odd numbers all the terms are in AP with a common difference 2.

→ So the first term is a.

→ Second term, b= a+2

→ Third term, c = b+2 = a+2+2 = a+4

→ Fourth term, d = c+2 = a+4+2 = a+6

→ Fifth term, e = d+2 = a+6+2 = a+8

→ So average=( a+b+c+d+e)/5

→ Average = (a+(a+2)+(a+4)+(a+6)+(a+8))/5

→ Average = (5a+20)/5

→ Average = a+4
