Answer:
- an = 3(-2)^(n-1)
- 3, -6, 12, -24, 48
Step-by-step explanation:
These variable names, a1, r, are commonly used in relationship to geometric sequences. We assume you want the terms of a geometric sequence with these characteristics.
a1 is the first term. r is the ratio between terms, so is the factor to find the next term from the previous one.
a1 = 3 (given)
a2 = a1×r = 3×(-2) = -6
a3 = a2×r = (-6)(-2) = 12
a4 = a3×r = (12)(-2) = -24
a5 = a4×r = (-24)(-2) = 48
The first 5 terms are 3, -6, 12, -24, 48.

The explicit formula for the terms of a geometric sequence is ...
an = a1×r^(n -1)
Using the given values of a1 and r, the explicit formula for this sequence is ...
an = 3(-2)^(n -1)
Answer:
i would say be smart and actually circle the x but i actually think its the smaller triangle
Step-by-step explanation:
B is correct
I just took it
8 ÷ 0.001 = 8 000
a) 8 ÷ 0.0001 = 80 000
8 ÷ 0.001 = 8 000
b) 8 ÷ 0.01 = 800
8 ÷ 0.001 = 8 000
8 ÷ 1/10 = 8 ÷ 0.1 = 80
c)8 ÷ 0.01 = 8 000
Answer:
100
Step-by-step explanation:
Write in an equation:
4=4%x, then divide 4% from both sides, and then you get 100.
