And now for something comletely different, as a well known TV series once said.
What is the next number ib this series?
1, 4, 10, 20, ?
And for the super clever of you there is an additional question (for extra points). Why did I think of this as I was having my lunch? Need a clue? Well ... I'll tell you what I had if you like.
Chicken and Bacon sandwich
2 snack pork pies
a small packet of cherry tomatoes
There, that's much clearer now isn't it? *evil laugh*
I'm off now to finish eating my fruit. I look forward to your comments.
