put a + b in brackets because your multiplying a and b three times

6√2 + 4 √32
try to get the same number "2" remaining under the root sign by finding what # times 2 gives 32
6√2 + 4√2×√16
since 16 is a perfect Square √16 gives 4
therefore.
6√2 + 4 ×4 √2
6√2 +16√2
these are Like terms so add them
which would give u
22√2

A sequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an =

Licemer1 [7]

I think you mean $a_n= \frac{a_{n-1}}{a_{n-2}}$
basically that measn yo divide that term by the previous term
ok

a3=a1/a2=1/2
a4=a3/a2=(1/2)/2=1/4
a5=a4/a3=(1/4)/(1/2)=1/2
a6=a5/a4=(1/2)/(1/4)=2
a7=a6/a5=2/(1/2)=4
a8=a7/a6=4/2=2
a9=a8/a7=2/4=1/2
a10=a9/a8=(1/2)/2=1/4
ok, so notice a pattern
a3=a9
a4=a10
I therefor conclude that $a_n=a_{n+6w}$ where w is a whole number
and n>2ok, so
241=6*39+7
so therefor
$a_{241}=a_{7+6(39)}$
therefor the 241th term is same as a7 or 4

I say a241 is 4
