In a geometric sequence, the numbers are found by multiplying each number by a fixed amount called a common ratio(r).

a1....this is ur first number....so since a1 = 3, ur first number is 3...and to find ur next numbers, multiply each number by r, the common ratio (which equals 0.5)

first number = 3.......3 x 0.5 = 1.5
second number = 1.5......1.5 x 0.5 = 0.75
third number = 0.75

si the first 3 terms are : 3, 1.5, 0.75
