You are given a table in which each row represents the coordinates of points.  For example, in the first line, we have x=-7 and y=5.  Work through the four given equations, one at a time, subbing -7 for x and 5 for y; is the equation still true?  If yes, then you have found the correct answer.  B is the exception; I'd suggest you check out equations A, C and D first, before focusing on B.

Example:  D:  (5)-5 = 2((-7) + 7) leads to 0 = 0.  Is that true?  If so, D is likely the correct answer.

Suppose that the second term of a geometric sequence is 4 and the sixth term is 16. Find the fourth term
Kaylis [27]

Answer:

  • 8

Step-by-step explanation:

<h3>Given GP</h3>
  • a₂ = 4,
  • a₆ = 16
<h3>To find</h3>
  • a₄ = ?
<h3>Solution</h3>
  • a₂ = ar = 4
  • a₆= ar⁵ = 16

<u>Substitute ar in the second equation</u>

  • ar⁵= 16
  • 4r⁴ = 16
  • r⁴ = 4
  • r = √2

<u>Then finding a₄</u>

  • a₄ = a₂*r² = 4*(√2)² = 4*2= 8
