What's the recursive formula of the geometric sequence below? 2, 6, 18, 54, 162, 486, ...

a1 = 2; an = an–1 ∙ (3)n–1 for n ≥ 1

a1 = 2; an = an–1 ∙ (3) for n ≥ 2

a1 = 3; an = an–1 ∙ (2)n–1 for n ≥ 2

a1 = 2; an = an–1 ∙ (2) for n ≥ 1

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
