## What is the secret to this?

What is the secret to this?

A1

C1

E3

H3

What comes next?

I2.

Each entry is a letter, in alphabetical order starting with A, followed by the number of occurrences of that letter in the phrase “What is the secret to this”.

There’s one ‘a’, thus we get A1. There are no ‘b’s so it doesn’t appear, then there’s one ‘c’, and so on.

## Wily Winifred and the Case of the Odd Numbers

Mrs. Shine was having a rough day and wanted a break. So she asked her class to calculate the sum of the first 50 odd numbers. In a few moments, Winifred was at her desk with the correct answer of 2,500. Stunned, Mrs. Shine figured she must have gotten lucky, and sent precocious Winifred back to her seat with the task of finding the sum of the first 75 odd numbers. Again, Winifred returned in seconds with the correct answer (5,625).

How did Winifred find the answer so quickly?

Winifred, being the precocious child she is, realized there was a pattern when computing smaller sums of odd numbers.

First 3: 1 + 3 + 5 = 9

First 4: 1 + 3 + 5 + 7 = 16

First 5: 1 + 3 + 5 + 7 + 9 = 25

Do you see the pattern like our dear friend Winnie?

For the first *n* odd numbers, the sum is equal to n^{2}. Thus the first 50 is 50^{2}, or 2,500, and the first 75 is 75^{2}, or 5,625.

Solve this one carefully!

230 – 220 x 0.5 = ?

You probably won’t believe it, but the answer is 5! How can this be true?

The answer is 120, and 5! = 5 × 4 × 3 × 2 × 1 = 120

I haven’t figured this out yet. Bad apple doesn’t really fit with the lowercase letters. They’re both vowels, but I don’t know if that’s relevant.
