Write an equation for the nth term of each geometric sequence:
1) 2,-6,18,…
2) 5,10,20,…

see explanation

Step-by-step explanation:

The nth term of a geometric sequence is

= a₁

where a₁ is the first term and r the common ratio

(1)

a₁ = 2 and r = = = - 3 , then

= 2

(2)

a₁ = 5 and r = = 2 , then

= 5

answer: true

step-by-step explanation:

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
