You can always draw a straight line between two points, so 2 points are always collinear.
However, coplanar means that the two points fall within the same plane. If you’re describing two different points from two different planes, they wouldn’t be collinear, but if they were on the same, they would be collinear.
We can conclude from this information that the answer is B.

Hope this helps!

If an=24, which recursive formula could represent the sequence below? ...,24,88, 664, 8408A) An=(An-2)^2 + An-1 ; A1=2B) An= 3An

Rudik [331]

When we substitute $n = 4$ , we get...

$a_{n-3}=a_1\\ \\ a_{n-2}=a_2\\ \\ a_{n-1}=a_3\\ \\ a_n=a_4$

Comparing the given sequence: 24, 88, 664, 8408, we get

$a_{n-3}=a_1=24\\ \\ a_{n-2}=a_2=88\\ \\ a_{n-1}=a_3=664\\ \\ a_n=a_4=8408$

We need to substitute the above values in each option and check which is TRUE.

----

<u>Option A</u>

$a_n=(a_{n-2})^2+a_{n-1}, a_1=2\\ \\ a_n=(88)^2+664=7744+664\\\\a_n=8408 (TRUE)$

<u>Option B</u>

$a_n=3a_{n-1}+16\\ \\ a_n=3(664)+16\\\\a_n=2008 (FALSE)$

<u>Option C</u>

$a_n=(n)a_{n-1}-8\\ \\ a_4=(4)a_3-8=4(664)-8\\\\a_4=2648 (FALSE)$

<u>Option D</u>

$a_n=2a_{n-2}+7a_{n-1}\\ \\ a_n=2(88)+7(664)\\ \\ a_n=4824(FALSE)$

Conclusion:

Option A is the correct answer.
