Question

post-23333

Heres another one.

Really dunno how to solve as correct method use is different from what i learnt last time.

 Thanks again.

Answer

One more alternative solution.

Alternatively,
120/5 = 24 (the number in the middle)
24 – 6 = 18
24 – 3 = 21
24 + 3 = 27
24 + 6 = 30 

Ans : 18, 21, 24, 27 and 30.

The 5 numbers are (n – 6), (n – 3), n, (n + 3), (n + 6)

Total: 5n = 120

n = 24

n – 6 = 18

n – 3 = 21

n = 24

n + 3 = 27

n + 6 = 30
