Answer 1

Answer:

Number= 7

Step-by-step explanation:

7+7+7=21

Answer 2

Answer:

5

Step-by-step explanation:

Let's Assume the number be x

then three consecutive odd numbers be- x, x+2, x+4

ATQ,

We have,

x + (x+2) + (x+4) = 21

x + x + 2 + x + 4 = 21

3x + 6 = 21

3x = 21 - 6

3x = 15

x = 15/3

x = 5

So, three consecutive odd numbers are

x = 5

x+2= 7

x+4=9
