Example 8 Find all pairs of consecutive odd natural numbers, both of which are largerthan 10, such that their sum is less than 40. |
|
Answer» Let the two consecutive odd positive integer be x and x+2.Both number are greater than 10 Thereforex>10 Also sum of the two integers is more than 40So, x + x + 2 < 40=>2x + 2 < 40=>2x < 40-2=>2x < 38=>x < 19 Since x is an odd integer number greater than 10 and less than 19. So, x can take values between 11, 13, 15, 17 Therefore, all pairs are(11, 13), (13, 15), (15,17) |
