2*16 + 8

32 + 8

b) For the seventh answer you get

2n^2 + 2n See diagrams for the number of matchsticks to be used.

n 2n^2 + 2n

1 2*1^2 + 2*1

1 2 + 2

1 4

2 2*2^2 + 2*2

2 2* 4 + 4

2 8 + 4

2 12

3 2*3^2 + 2*3

3 18 + 6

3 24

What an extremely interesting sequence. I'll bet not one person in 100 could get this without the match stick diagrams. I'm sorry I didn't read the question more carefully.

These values are the unique weights of the juveniles.

In other words, any value other than 5, 6, 10 or 13 can not be regarded as weights of the juveniles.

Hence, the unique weights are 5, 6, 10 and 13
