HW: Finding the sum of nth odd, even, & consecutive #s

Aim 1: to find the sum of the first "n" odd integers

If you didn't get the nth term in class, create and complete a term and value chart. Label the top row "# of odd integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:

• 1
• 1+3=?
• 1+3+5=?
• 1+3+5+7=?
• 1+3+5=7+9=?

Practice Problems:

1. Find the sum of the first 80 odd integers.
2. Find the sum of the first 90 odd integers.
3. Find the sum of the first 100 odd integers.
4. 1+3+5+...+253=?
5. 1+3+5+...+987=?
6. 1+3+5+...+1269=?
7. 255+257+259+...+757=?
8. 339+341+343+...887=?
9. 551+553+555+...+1111=?

Aim 2: to find the sum of the first "n" even integers

If you didn't get the nth term in class, create and complete a term and value chart. Label the top row "# of even integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:

• 2
• 2+4=?
• 2+4+6=?
• 2+4+6+8=?
• 2+4+6+8+10=?

Practice Problems:

1. Find the sum of the first 250 even integers.
2. Find the sum of the first 700 even integers.
3. Find the sum of the first 1000 even integers.
4. 2+4+6+...+500=?
5. 2+4+6+...+1000=?
6. 2+4+6+...+1600=?
7. 450+452+454+...+988=?
8. 234+236+238+...+1290=?
9. 886+888+890+...+2000=?

Aim 3: to find the sum of the first "n" consecutive integers

We didn't get to figure out the nth term in class, but you can now create and complete a term and value chart. Label the top row "# of consecutive integers". Label the bottom row "Sum". Then, calculate the sum by completing the following:

• 1
• 1+2=?
• 1+2+3=?
• 1+2+3+4=?
• 1+2+3+4+5=?
• 1+2+3+4+5+6=?

Practice Problems:

1. Find the sum of the first 20 consecutive integers.
2. Find the sum of the first 100 consecutive integers.
3. Find the sum of the first 1600 consecutive integers.
4. 1+2+3+...+500=?
5. 1+2+3+...+950=?
6. 1+2+3+...+4280=?
7. 450+451+452+...+921=?
8. 263+264+265+...+900=?
9. 567+568+569+...+789=?
10. 678+679+680+...+1616=?

P.S. You may choose whatever screen name you want. I recommend that you use your last name and first intial so that I may recognize you if I am looking to give you credit for logging on. If, however, you don't use your name in your screen name, then you MUST identify yourself in a posting. For instance, if your screen name is ThePuertoRican, then obviously I have no idea who you are. You will have to write your name in a posting and identify yourself.

Welcome message

WELCOME!!!

You have entered the danger zone. Warning! Warning! Warning! (sirens blaring in the background....woop! woop! woop!) You have just arrived at your new blog site. This is the place where I will post your homework assignments, news events, and notices of upcoming tests. It is also a place where you can communicate with your fellow geometricians as you make that slow, treacherous journey through my Geometry Honors class. I LOVE this course and take great pride in teaching it. It is my hope that you will eventually develop the same passion for it that I have. If not, at least gain enough knowledge to perform at a very high standard on the SAT or ACT.

Anyhoo, use this blog as a means of communicating with your fellow classmates. For instance, if you don't know how to do problem number 11 tonight, then you can post it. Hopefully, someone will read your posting and respond with a hint or an explanation of how to arrive at the answer. Use this blog to your benefit.

Also, there are helpful mathematical links on the left hand side. Click on each of them to see what they look like. Every now and then, I will offer extra credit for logging in to some of these sites.

Until then, happy blogging!!!!

Ms. Chan
