Brain Challenges for YouOctober 2021
Lots of Working Memory practice for you this month.
Answers: 25 and 4
#1 – Move down and to the right.
The difference between each successive pair of numbers increases by 1.
5 + 2 = 7, 7 + 3 = 10, 10 + 4 = 14, 14 + 5 = 19, 19 + 6 = 25
#2 – Add 2 adjacent numbers.
Subtract 6 to get the number below and between them.
(2 + 5) – 6 = 1 , (5 + 7) – 6 = 6, (7 + 8) – 6 = 9
(1 + 9) – 6 = 4
e.g. (2 + 5) – 6 = 1. This calculation is at the top left of the triangle, with the solution – the 1 – situated between and below the 2 and the 5.
The second line then becomes (1 + 6) – 6 = 1 and this calculation is again placed between and below the 1 and the 6.
Same for (6 + 9) – 6 = 9 the result placed between and below.
Then the third line: (1 + 9) – 6 = 4

Riddle 1: A bar of soap
Riddle 2: Time
How to get to the other side?
Three sturdy trampers come to a deep river and there seems to be no way to cross.
Two young boys agree to help but the canoe can hold only two boys or one man..
Can you work out how the three trampers can reach the other side?
Both of the boys go to the far side. One hops out and the other returns to the three men.
The first man crosses alone, leaving one boy on each side.
The boy on the side where the first man has been left then crosses back and picks up the other boy who then takes the first boy back to the other bank, drops him there and crosses back.
The second man.crosses the river to where one boy is waiting.
That boy crosses the river, picks up the other boy and they both cross back again, leaving one boy with the two men who have safely crossed.
A rather tired boy then rows back to the other side and the third tramper crosses safely.
The waiting boy rows back to pick up his friend and some very grateful trampers carry on their way.
