Try to take a look at the successive differences (ie $a_{n+1}- a_{n}$)

Then try to get a formula for $a_{11}$

ah okay

#

Find the common difference of each AP. Then find a formula for the nth term Tn.
a log3 2, log3 4, log3 8, . . .

#

how does one

#

i dont log

ebon helm
#

log?

sour lantern
#

its a AP of

logv3 2, logv3 4, logv3 8, . . .

#

tiny 3

#

but like how is that going up by logv3 2?

ebon helm
#

If the two is in the exponent, then laws of logarithms let you take it to the outside so you get $$a_{n} =log_{3}n$$

for this: Ive got the AP but dont know how they got the nth

ebon helm
#

The nth term is in the form of $a_{n}$ and you plug in n to get that term
