to find common ratio divide next term by the previous one \[\large\rm r=\frac{ a_2 }{ a_1}~~or~~\frac{ a_3 }{ a_2} \]a_2 = 2nd term a_3 = 3rd term

ratio between two numbers in geometric you will multiply the first by common ratio to get the nexxt one other way to solve for r is first term times r = 2nd term
Nnesha
  • Nnesha
\[\huge\rm a_1 \times r = a_2\] what is first term and what is 2nd one ?
Nnesha
  • Nnesha
aww i see
mckenzieandjesus
  • mckenzieandjesus
-4 and 36
Nnesha
  • Nnesha
i see what u did there it's `common ratio` not common difference
Nnesha
  • Nnesha
now first one is -4 2nd term is what ?
Nnesha
  • Nnesha
1st term , 2nd term , 3rd, 4th term..........
mckenzieandjesus
  • mckenzieandjesus
32?
Nnesha
  • Nnesha
2 comes after 1 so what's 2nd term in this sequence `–4, 8, –16, 32, . . .`
mckenzieandjesus
  • mckenzieandjesus
8
Nnesha
  • Nnesha
right so \[\huge\rm -4r=8\] solve for r
mckenzieandjesus
  • mckenzieandjesus
2?
Nnesha
  • Nnesha
hmm positive 8 divide by `negative 4` = ?
mckenzieandjesus
  • mckenzieandjesus
-32
Nnesha
  • Nnesha
divide not multiply
mckenzieandjesus
  • mckenzieandjesus
ohh
mckenzieandjesus
  • mckenzieandjesus
-2!
Nnesha
  • Nnesha
to find common ratio we should divide 2nd term by first one or 3rd term divide by 2nd term
Nnesha
  • Nnesha
right yahoo!
mckenzieandjesus
  • mckenzieandjesus
so i gueesed the right answer then :) thanku

  • mckenzieandjesus
2, –10, 50, –250, . . .
Nnesha
  • Nnesha
will try
Nnesha
  • Nnesha
find common ratio ?
mckenzieandjesus
  • mckenzieandjesus
yes
Nnesha
  • Nnesha
alright same steps try it!
Nnesha
  • Nnesha
divide any term with the previous one you can divide 4th by 3rd one 3rd one by 2nd one 2nd one by first one
