Question
UNIVERSITY OF EASTERN PANGASINAN 5. The sum of the first three terms of an AP is -3 while the sum of the first five terms is 10. What is the value of the first term? What is the common difference? 6. In a Geometric Progression, if the first term is x and the common ration is x", which term (the nth term ?) is x? 7. Find the sum of all integers between 90 and 190 if each integer is divisible by 17. (Hint. Consider 90.. [102, 119,.1871.190) 8. Insert four Geometric Means (GM) between 5 and 160. 9. If the 2nd term of a GP is 12 and the 5th is 216. Find the common ratio r. What is the sum of all the five terms. 5. The third term of a Geometric progression is 5 and the 6th term is -40, find the 8th term.
