tes
OpenStudy (iwanttogotostanford):
so the first one is right, what is the next one?? @sooobored :-)
OpenStudy (sooobored):
4*5= 20
OpenStudy (sooobored):
20 is the 2nd digit hence n=2

5^n+___ = 5
OpenStudy (sooobored):
where n= 2
OpenStudy (iwanttogotostanford):
so it would be D right???
OpenStudy (sooobored):
2-2=0
5^0=1
therefore the 2nd digit would be 4 not 1
OpenStudy (sooobored):
not 20 dunno where 1 came from

oh so ti is B??
OpenStudy (sooobored):
2-1=1
5^1=5
therefore the 2nd digit would be 20
since this works, lets check the 5th term
i dont have a calculator but make sure
4*5^4=2500
OpenStudy (sooobored):
if it does then thats the right answer
OpenStudy (iwanttogotostanford):
well i need verification please help with that i understand but i need verification
OpenStudy (sooobored):
well, checking the 5th term is the verification

we know it works for the 2nd term, so we use the fifth term to be completely sure
OpenStudy (sooobored):
i mean, the other way to be completely sure that B is the answer is to try applying the 2nd term/ n=2 to all the other equations and trying to get 20
OpenStudy (iwanttogotostanford):
so it is B? I checked but i still need verification here too please
OpenStudy (sooobored):
YESSSSS, have some confidence man
