HELP ME Which of the following choices is the explicit formula for the following geometric sequence? -0.1, 0.04, -0.016, 0.0064, -0.00256, ... A.an = 0.1(-0.4)n-1 B.an = -0.1(0.4)n-1 C.an = 0.1(0.4)n D.an = 0.4(-0.4)n-1 E. an = -0.1(-0.4)n-1

first find the common ratio 0.04/-0.1=?
xapproachesinfinity
  • xapproachesinfinity
the explicit formula for a geometric sequence is \(\Large a_n=ar^{n-1}\) a is the first term and r is the common ratio

0.4?
xapproachesinfinity
  • xapproachesinfinity
no

  • anonymous
i mean 1
xapproachesinfinity
  • xapproachesinfinity
-0.4
anonymous
  • anonymous
ok but that next number is gonna be a positive
xapproachesinfinity
  • xapproachesinfinity
yeah and it is positive there is an oscillation of sign because of that negative

o ok i got you
xapproachesinfinity
  • xapproachesinfinity
-0.1x-0.4=0.04 0.04x-0.4=-0.0016....
xapproachesinfinity
  • xapproachesinfinity
you continue like that to generate as many term as you like
anonymous
  • anonymous
so its a
xapproachesinfinity
  • xapproachesinfinity
so r=-0.4
xapproachesinfinity
  • xapproachesinfinity
no A is incorrect
xapproachesinfinity
  • xapproachesinfinity
first term is -0.1 not 0.1

so e
xapproachesinfinity
  • xapproachesinfinity
yes!
