smouse, re Q39. I have an answer that is very devious, can you tell me what you have, my answer is 70, arrived at by doubling each number then adding the previous number, this gives you:-
1, 2, 5(2+2+1),12(5+5+2),29(12+12+5),70(29+29+12) can this be correct
yes sun is a star in my opinion
youre way off with 39 its money i think but dont see that now with your numbers and i have posted it off but check it out
