- 1Sequence whose consecutive terms have common ratio.Geometric sequence
- 2What is the formula of geometric sequence?an = a1r^(n-1)
- 3Give the 2nd term of the geometric sequence with common ratio r=-3/4 and first term a1=4/3.a1= 4/3
a2=?
r= -3/4
a2= (4/3) (-3/4) = -1
a2 = -1 - 4According to the given in flashcard number 2, give the 3rd term of the geometric sequence with common ratio r=-3/4 and first term a1=4/3.a1= 4/3
a2= -1
r= -3/4
a3=?
a3 = -1(-3/4) = 3/4
a3 = 3/4 - 5According to the given in flashcard numbers 2 and 3, give the 4th term of the geometric sequence with common ratio r=-3/4 and first term a1=4/3.a1= 4/3
a2= -1
a3= 3/4
r= -3/4
a4=?
a4= 3/4 (-3/4) = -9/16
a4 = 9/16 - 6Determine the common ratio of the term 2,6,18,54,162,...162/54= 3
54/18= 3
18/6= 3
6/2= 3
r = 3 - 7Determine the 10th term of 5,10,20,...r= 10/5 = 2
a1= 5
a10=?
an= 5(2)^(10-1)
a10= 5(2)^9
a10= 5(512)
a10= 2,560 - 8Geometric sequence or not? 5,-5,5,-5,...Geometric sequence
