Answer:
10, 30, 90, 270, 810
Step-by-step explanation:
geometric sequence formula is ar^(n-1)
a is the first term which is 10
r is the common ratio which is 3 (i.e the second term divided by the first term)
n is called the nth term
....so we're looking for the fourth and fifth term
fourth term= 10*3^(4-1)
= 10*3^3
=10*27
=270
fifth term= 10*3^(5-1)
=10*3^4
=10*81
=810
