Friday's Maths Brain Teasers ? ❓

Miss has gone to bed willa. You can come into the dormitory and share my cakes if you’re quiet ?

I've argued with Miss but all to no avail willa.

I made it 40 then thought it was too easy so looked for the 'catch' and thought I'd found it, answer 96.

If we argue any more we'll get sent to bed without supper, which doesn't sound like a bad idea at all.

enjoy the rest of your day.

40 for me

If I had wanted the answer 96, I would have asked for the eighth term of the sequence.

Also I would have expected posters to state the equation for the n term, but I didn't.
It was meant to be simple, so that everyone could have a go. Phew! My brain hurts. ?

Now go to sleep everyone, except wila who is on a different continent!

PS, you should have been able to read my mind!!! ?

The thing is this: nowhere does it say you have to add in the total for the previous line. This part of the equation is absent, and we have to just guess it.

So my solution was calculated using a different 'absent' part, as follows:

1+4=5 became 1+1x4=5
2+5=12 became 2+2x5=12
3+6=21 became 3+3x6=21

You get my drift?

So it followed (well, for me of little brain that is) that:

8+11 became 8+8x11= 96

Not a sequence at all, but an additional element in the equation, just as the 'correct' answer has an additional element.

Right, I'll sit back down now Miss

40

Better late than never Katiel ?

Katie, this is an old Friday's puzzle. 3rd April.
The answer is given at the end of every day.

40?

THIS IS AN OLD PUZZLE, FROM WEEKS AGO, THE SOLUTION HAS BEEN ALREADY GIVEN

I post a new one every day, about 9am, keep your eye out if you want to join in! You are very welcome to do so.

It's good fun and some lovely posters.

But Miss is very strict.
Be warned.
(I am usually in trouble.)

Me too ?

I thought you were in detention- again, Doodle.
Who let you out?
