Astonishing Numbers

April 2, 2016

15 is an "astonishing number".  15 equals the sum of all of the integers from 1 through 5.

1 + 2 + 3 + 4 + 5 = 15.

The next "astonishing number" is 27.  27 is the sum of all of the integers from 2 through 7.

2 + 3 + 4 + 5 + 6 + 7 = 27.

204 is an "astonishing number".  204 is the sum of all of the integers from 20 through 4 (yes, we are going backwards, but that's OK).

20 + 19 + 18 + ... + 6 + 5 + 4 = 204.

891,406,343,154,063 is equal to the sum of all of the integers from 8,914,063 through 43,154,063.

P.S.  I have finished my first cycle of chemotherapy.  It was rough, but I still have my lovely hair.  I will keep up the treatments.  But today has been the first day in a while that I felt like blogging.

I will try to get in a few more posts before my next cycle starts next Thursday.

I appreciate those of you who are praying for me.
