@PFEH.1999

OpenStudy (anonymous):

u mean this? \(\Large \sum_{i=1}^{\infty} 6 (3)^{i-1}\)

OpenStudy (anonymous):

Yess! Can you help? ;c

OpenStudy (anonymous):

i got 4374?

OpenStudy (anonymous):

let me check...

OpenStudy (anonymous):

2,184 6,558 27,993 167,961 These are the answer choices D;

OpenStudy (anonymous):

sry it seems some mistake has been made...let me check again.

OpenStudy (anonymous):

Okay :c

OpenStudy (anonymous):

sry ;) maybe have forgot all about sum :P you have to find the sum of i=1 up to i=7...so substitute i=1 and find it then substitute i=2 then find it and do this up to i=7 and then find sum of all of them: 4374 + 1458 + 486 + 162 + 54 + 18 + 6 = 6,558

OpenStudy (anonymous):

the second one ;)

OpenStudy (anonymous):

Aweh c: Thank you! Can you help me with a few more?

OpenStudy (anonymous):

sure ;)
