Arithmetic Means
- 1. Arithmetic Means Solomon Hippocrates S. Flores E. Rodriguez Vocational High School
- 2. Find the specified term for each arithmetic sequence. 1) 5, 8, 11, … 10th term
- 3. 2) 25, 20, 15, … 8th term
- 4. 3) 1, 6, 11, 16, … 6th term
- 5. 4) 10, 6, 2, -1, … 17th term
- 6. 5) 99, 88, 77, 66, … 18th term
- 7. Consider the following sequences: 1) 12, 26, 40, … 2) 300, 375, 450, … 3) 36, 33, 30, … Do younotice anything?
- 8. Observe that… 1) 12, 26, 40, … 2) 300, 375, 450, … 3) 36, 33, 30, … In general, a1, a2 and a3 are three consecutive terms of an arithmetic sequence, then the average of the first and the third terms is the middle term, We can say that a2 is the arithmetic mean of a1 and a3.
- 9. The arithmetic means are the terms included between any two consecutive terms of an arithmetic sequence. The first and the last terms in an arithmetic sequence are called arithmetic extremes while the terms in between are the arithmetic means.
- 10. 3. Insert five arithmetic means between -4 and 38. 4. Insert six arithmetic means between -20 and -76. 5. If there are 14 arithmetic means between 25 and 85, find the 7th arithmetic mean. Consider the following: 1. Find the arithmetic mean of 15 and 71. 2. Find the arithmetic mean between -8 and 24. We can also insert more thanone arithmetic mean between any two consecutive terms in an arithmetic sequence.
- 11. Solve the following: 1. Insert four arithmetic means between 2 and 14. 2. Insert four arithmetic means between -2 and 38. 3. Find an arithmetic mean between 49 and 9. 4. What are the three arithmetic means between 6.2 and 11? 5. If there are 8 arithmetic means between 10 and 50, find the 6th arithmetic mean.
- 12. Values integration In his book Good to Great: Why Some Companies Make the Leap.. And Others Don’t, Jim Collins wrote, “By definition,it is not possiblefor everyone to be above the average.” Do you believe on this or not? Why?
- 13. Complete the following statements: 1. When three terms form an arithmetic sequence, the _____________ is called the arithmetic mean between the two terms. 2. The terms included ___________any two ____________ terms of an arithmetic sequence are called ______________. 3. The first term and the __________ in an arithmetic sequence are called arithmetic ___________ while the _______________ are the arithmetic means.
- 14. Insert the indicated number of arithmetic means between the two given numbers. 1) three; 10 and -10 6) four; ½ and 1/32 2) two; -3/4 and 1/4 7) three; 10 and -10 3) five; 4 and 40 8) four; 3 and 18 4) six; 1 and -20 9) five; 0 and -12 5) six; -23 and -44 10) three; 10 and 58
