Just like the same .. kaso nga lang yung common ratio ang hahanapin ....

so α∧n≡α∧1r∧n-1
3125≡5(r∧4)
so divided by 5
so 625≡r∧4
dn i fofourth root natin para mawala yung 4 na exponent sa r
so yung answer is equals to 5

0
so yung a sub 2 is equals to 25
a sub 3 is equals to 125 dn a sub 4 is equals to 625
tnx po!!! alam ko po kc ung common ratio nila kaso need po ng formula ! btw thanks a lot po!!
pwede po bang paspecify nung part po na 625=r4???
pano po natanggal ung 4th root?
