get mo po muna yung common ratio po nung geometric sequence para po malaman nyo yung nth term

get mo po muna yung common ratio po nung geometric sequence para po malaman nyo yung nth term
2nd term ÷ 1st term to get the common ratio (r) then multiply the preceding term to get the next term or divide it to get the previous term


sana nakatulong.nakalimot agad ako topic lang namin din to last quarter eh.

Thank you paps try ko poo, nalilito kase ako
 
1. 7th term
2. 1/4
3. 83.333
4. 11
5. 8625
Same answers.

1.
48 = 3072*(1/2)^(n-1)
Solving for n, n = 7

2.
(1/108)/(1/2125764) = (r^(4-1))/(r^(13-1))
Solving for r, r = 1/3

1/108 = a1*(1/3)^(4-1)
Solving for a1, a1 = 1/4

3.
r =100/-20 = -1/5

S20 = 100*(1-(-1/5)^20)/(1-(-1/5)
S20 = 250/3

4.
d = 7

396 = (n/2)(2*1 + (n-1)*7)
Solving for n, n = 11

5.
d = 2 (consecutive odd integer)

99 = 1 + (n-1)*2
Solving for n, n = 50

S50 = 50*(1+99)/2
S50 = 2500
