Hello,
4. you have sequences defined by the first term and a recursive relation.

Take n = 2, it gives
, right?
But you know 
so 
This is the second term. You are asked to find the first three terms.
Now, let's take n = 3

So the first three terms are 3, 6, 12.
6.

8.

10.

Do not hesitate if you have any question.
Thank you
I am thinking it will be d . Functions
We have to calculate the height of a cylinder : h2 = ( 45 - 2 · 15 )/ 2 = 15 / 2 = 7.5 mm
Volume of the bottom of the hourglass:V = 1/3 r² π h1 + r² π h2 = = 1/3 · 6² · 3.14 · 15 + 6² · 3.14 · 7.5 = = 1/3 · 36 · 3.14 · 15 + 36 · 3.14 · 7.5 = = 565.2 + 847.8 = 1,413 mm³The rate is 10 π mm³/ sec = 31.4 mm³/secTime = 1,413 : 31.4 = 45 sec.Answer: It will take 45 seconds.
