Is the following sequence arithmetic or geometric, and what is the common difference (d) or the common ratio () of the sequence? 7 21 63 2\'4 8 1, Arithmetic, d=1.5 2. Geometric, r 1.5 3, Geometric, d = 3 4, Arithmetic, r = 3

Solution

7/2 , 21/4 , 63/8 ...

the following sequence is geometric as there is a common ratio between two terms

common ratio is

r = 21/4 / 7/2 = 1.5

hence , option 2 is correct
