Brain Teasers

1. What is the next letter in this series?
O T T F F S S E N ?
2. Divide 100 by ½ and add 10.
What do you have?
The first one is not as hard as you think, the second is not quite as simple as you think.

Katie is standing beside me and said the second one is easy. 60

Tom and Lillie Wilkinson said...

Echo is saying that it is 210.

Della Hill said...

Echo is right.
When you divide by 1/2, you actually multiply by 2.
So 100 X 2 = 200, 200 + 10 = 210.

Good job.

I'll agree with Echo on the second question.

The sequence for the first one is

o, t, t, f, f, s, s, e, n, t, e, t, t, f, f, s, s, e, n, t, t, t, t, t...

If this puzzle was applied to someone from Mexico the answer would be

u, d, t, c, c, s, s, o, n, d, o, d, t, c, q, d, d, d, d , v, v, v, v, v, v...

If this puzzle was asked to someone in France their answer would be to surrender and wait for the US to come and save thier bacon again.

Della Hill said...

Correct, correct, and absolutely right.
And you made me laugh too.
So has anyone else figured out what the sequence is?

Della Hill said...

The sequence is one, two, three, four, etc.
The letters of the sequence are the first letter in each number counting from one.
So when Mike answered he gave the answer in spanish as well as english.
