Question 982202
<pre>
At 12:00 Midnight ("Saturday night", actually beginning Sunday morning),
the clock strikes 12 times.
At 1 AM Sunday morning it strikes 1 time.
At 2 AM Sunday morning it strikes 2 times.
...

At 11 AM Sunday morning it strikes 11 times.

That's the sum of the integers 1 through 12.

{{{S[n]=expr(n/2)(a[1]+a[n])}}}

{{{S[12]=expr(12/2)(1+12)}}}

{{{S[12]=6*13}}}

{{{s[12]=78}}}

It strikes 78 times twice a day for 7 days. 

That's 14x78 = 1092 times a week that it strikes.
