![]() ![]() The lengths of the rectangular triangle sides with a longer leg of 12 cm form an arithmetic sequence. What numbers did the pages have on the page that was torn from the book?ĭetermine the area of a right triangle whose side lengths form successive members of an arithmetic progression, and the radius of the circle described by the triangle is 5 cm.įind the remaining unknown characteristics in the finite geometric sequence, if given: a1 = 18, an = 13122, sn = 19674, n =?, q =? ![]() The sum of the page numbers of all the remaining pages is 15,000. How many layers are needed to deposit 100 tubes if the top layer has 9 tubes? How many tubes are in the bottom layer of tubes? Iron tubes in the warehouse are stored in layers so that each tube's top layer fits into the gaps of the lower layer. If the sum of four consecutive terms of a geometric progression is 80 and the arithmetic mean of the second and fourth terms is 30, then find terms. How many terms does the sequence have if a1=4, Sn=589, d=3, n=? Determine the remaining sides of the triangle. The sides of a right triangle form an arithmetic sequence. How many are the total rows in the cinema?ĭetermine the second term and the quotient GP if a3 = 48.6 a1 + a2 = 6 In the cinema are 1656 seats and in the last row are 105 seats, in each next row 3 seats less. The sum of three numbers in GP (geometric progression) is 21, and the sum of their squares is 189. The three numbers that make three consecutive members of an arithmetic sequence have a sum of 60 and a product of 7500. The arithmetic sequence is given: S n=2304, d=2, a n=95 Calculate a 1 and n. If the common difference is 10, find the first term. The product of the third and second terms of the arithmetic progression is 3000. ![]()
