Find x such that x - 4, x, and 3x - 8 are three consecutive terms in a geometric sequence
Nitella [24]
In a geometric sequence dividing any term by the term before it yields the common multiplier.
Then x/(x+8) = (3x-8)/x
Solving for x:  reduces to x^2-10x +16 factor into (x-2)(x-8)
Then x = 2 or 8
2 produces a sequence of -2, 2, -2 ...

Answer:

See below

Step-by-step explanation:

Let the number of Payday be p and Baby Ruth be b

<u>Then sub of the candy bars:</u>

  • p + b = 220
  • Payday candy bars worth ⇒ $2p
  • Baby Ruth candy bars worth ⇒ $3b
  • Total ⇒ $600

1. <u>Required equations:</u>

  • p + b = 220
  • 2p + 3b = 600

2. <u>Solving by substitution:</u>

p = 220 - b, consider it in the second equation

  • 2(220 - b) + 3b = 600
  • 660 - 2b + 3b = 600
  • 660 + b = 600
  • b = 660 - 600
  • b = 60
