Picture with question

Answer 1

By the picture it looks like they keep multiplying it by 3 so you just do 90*3 =270 and 270*3=810 so your next to answers should be 270 and 810

Answer 2

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
