Question

a) The sum of three consecutive odd numbers is 63. Find the numbers.

Answer 1

Step-by-step explanation:

let numbers be x - 2, x , x+2

so according to condition

x - 2 + x + x + 2 = 63

3x = 63

x = 21

x - 2 = 21 - 2 = 19

x + 2 = 21 + 2 = 23

Number are 19, 21, 23

Answer 2

Answer:

the number are 9,11 and 13

Step-by-step explanation:

given : the sum of three consecutive odd number is 33

to find : what are the number ?

solution:

let the three consecutive odd number are x,x+2,×+4

according to question,

the sum of three consecutive odd number is 33

x+×+2+×+4=33

add like terms

3×+6=33

subtract 6both side 3×=27

divide by 3both side ,

3×/3 =27/3

×=9

so ,the consecutive odd number are

×=9

×+2=9+2=11

×+4=9+4=13

therefore ,the number are 9,11 and 13
