1) A drive-in theater has spaces for 20 cars in the first parking row, 22 in the second, so on. If there are 21 rows in the theater, find the number of cars that can be parked. (12)Find the nth tern of the geometric sequence with given first term a and common fourth term? (a) a = 7 (b) a = r=4 (13) Find the first five terms of the sequence, and determine whether it is geometric. If Tind the common ratio, and express the nth term of the sequence in the standard form (a) a = 2(3)" (b) (a) -1 3*-1 (b) Ex-16 64*-1 (14)Find the sum. 32 Find the first and nth terms.. (15) The fourth term is 12 and the seventh term is (16) The third term is-18 and the sixth term is 9216. Find the first and nth terms.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
