Find four consecutive odd numbers which add up to 120?

The four consecutive odd numbers which add up to 120 are 27, 29, 31 and 33.

It can be found out as follows:

Let 'x' be the smallest odd number.

The next odd numbers will be 'x+2', 'x+4', 'x+6'.

The addition of these four numbers will give 120.

Therefore,

x+(x+2)+(x+4)+(x+6)=120

4x+12=120

x+3=30

Therefore, x=27.
