Answer:
aₙ = (-1)ⁿ2(3)ⁿ⁻³
Step-by-step explanation:
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
We can get the value for r by dividing aₙ by aₙ₋₁.
a₄/a₃ = 6 ÷ (-2)
a₄/a₃ = -3
r = -3
=====
a₁ = -2/9
aₙ = (-2/9)(-3)ⁿ⁻¹
aₙ = (-2/3²)(-3)ⁿ⁻¹ Factor out the 3s from the 9
aₙ = -2(3²)(-1)ⁿ⁻¹(3)ⁿ⁻¹ Factor -1 from and -3
aₙ = (-1)(2)(-1)ⁿ⁻¹(3)ⁿ⁻³ Combine like terms
aₙ = 2(-1)ⁿ⁻²(3)ⁿ⁻³ Multiply the -1 term by (-1)² (=1)
aₙ = (-1)ⁿ2(3)ⁿ⁻³
The (-1)ⁿ term makes the terms alternately positive and negative.
Answer:
28
Step-by-step explanation:
1 * 2 equals 2 so when you multiply two from one you gave to then after that you multiply 2 * 7 equals 14 million * the answer that you got from the first one and you added to the second number and then you multiply them together they equal 1 + 2 + 14 * 1.2=2
2.7=14
