Q. What is the next number in this sequence...and why?
...and what might precede the '1' in the same sequence?

1, 4, 7, 10, ?

Could be 13, 1+3 =4; 4+3=7;7+3 =10
-2...Too easy I suspect.

Its not 13

Is this music-related in some way?

Otherwise I may find myself barking in the wrong orchard.

...I should've said - its not music related, no :)

That's me out.

:lol:
its not maths related either

Gauge wire values?
edit# ive seen them written down somewhere like that.

It's probably the last four books he's read. One Flew Over The Cuckoo's Nest and Enid Blyton's Secret Seven On The Trail are easy enough, but I'm damned if I can think what 4 and 10 might be.

Four Just Men by Edgar Wallace and Ten Little Niggaz by Eazy-E (as told to Agatha Christie). Obvious, really.

pipe diameters,??
0·8 and 12,

Its not wire gauges, pipe diameters ...or the last 4 books I read...no...(although I do have an Edgar Wallace on the go...'The Crimson Circle')

ok...this number sequence originated in America...although its now more common elsewhere/
It is based on a type of ignorance...or, more kindly, a human foible.

The average number of guns per household, measured every 5 years.
Last count 2002, this years figures 12 guns on average per household.
The number of donuts cops eat, according to rank, per hour. Station Captains are on 10 an hour. Commisioners 14 per hour.
The average amount of time spent watching TV.

:lol:

Ok - my quiz is very hard. The question occurred to me when I was leaving for work the other morning. I live in a block of flats.

68.5?

now you just beeing silly

The answer is 14. There is no 13th floor in many blocks of flats, for superstitious reasons. Therefore, reading downwards from the top, the list of floors would go: 1, 4, 7, 10, 14.

And 1 would be preceded by G.

The mystery is solved. Well done.
I was struck when in the lift the other day that this might make a good quiz question...of the type they ask in Sunday supplement magazines.

There is no 13th floor in our building. The lift goes from 12 to 14. The buttons on the panel indeed go 1, 4, 7, 10, 14, 17 ...(there are 3 columns of buttons).

I wish I had a good prize to send you....this smilie will have to suffice

That's remarkable.

There is no 4th floor in many Chinese blocks of flats.
Similar reasons, 4 can sound the same as "death" or "die" I think.

Bollocks! ...the answear is 1, with 1 preceded by 10.
