38. A geometric sequence is
a sequence where each
term after the first is
obtained by multiplying
the preceding term by a
nonzero constant called
the common ratio.
48. Task
A scientist is studying a type of bacteria. The
number of bacteria over the first four days is
shown below.
How many bacteria will there be on day 7?

51. a. Who among them got the
correct answer? Justify.
b. If you are one of the students
in the situation who gets the
right answer how will
convince your friend?

53. TRIAD ACTIVITY /
Math Brochure Project
Direction: Make a leaflet/brochure showing
information on arithmetic and geometric
sequences. Include examples and related
problems.
54. YOU MAKE ME SMILE (Version 3.0)
Directions: On the happy side of your emoji
stick, write the things that you have learned
about the lesson. While on the sad side, write
the things that confused you or the things
that you want to learn about.
Editor's Notes
Okay! It seems that you can still recall our lesson last time. Just keep your emojis because later on we’ll be using that in our succeeding activities or if you wish to recite just raise your emoji.
The activity that we did a while back featured the two common emojis found in social media, right class?
The happy and the sad! In life, no matter how much we want to be happy all the time there are still moments we can’t avoid sadness, it’s okay because we will never know the true meaning of happiness if we do not know how it feels like to be sad but just like mathematics there’s also formula for happiness:
Francine kindly read the formula.
Thank you Fancine!
Today we will tackle the continuation of the concept of geometric sequence and we will study to find the nth term of a geometric sequence.
In our first activity you did the two common emojis, this time, for our next activity we will do a guessing game using emojis as a clue.
May I request Bernard to read the title and the direction of the game.

Thank you for your participation. In our activity, we decode the places in the Philippines using patterns. I hope someday we’ll get to explore the places mentioned in Activity 2. But as for now, let's first explore the formula for finding the nth term of a geometric sequence.
By the way, what is a Geometric Sequence again?
Let me introduce the topic by presenting to you situations on geometric sequence. Let us study example 1.
b. 1. Proper hygiene - wash your hands frequently and thoroughly, avoid touching your eyes, avoid too much exposure to sunlight or even radiation, healthy diet, take vitamins, take enough rest, exercise
c. When we say that prevention is better than cure, it essentially means that it is better to stop something before it happens instead of having to repair it or deal with its consequences after it has already been done.

-ang pag iwas ay mas Mabuti kaysa pagalingin
Let’s proceed to example 2. John will you read the problem?
Here is the solution:
a. For 7 days
For Lina: Given: 𝑎 1 =1 r = 2
Formula: 𝑎 𝑛 = 𝑎 1 𝑟 𝑛−1
Solve: 𝑎 𝑛 = 𝑎 1 𝑟 𝑛−1
𝑎 7 =1( 2) 7−1
𝑎 7 =1( 2) 6 𝑎 7 =64
For Lina: Given: 𝑎 1 =1 r = 3
Formula: 𝑎 𝑛 = 𝑎 1 𝑟 𝑛−1
Solve: 𝑎 𝑛 = 𝑎 1 𝑟 𝑛−1
𝑎 7 =1( 3) 7−1
𝑎 7 =1( 3) 6 𝑎 7 =729
(b-e. Varied answers from students)
B. Maybe the amount of money they save for few days, weeks, or months is not that much but for those who will receive it is more than enough. Anyways, its not the amount but the thought that matters.
C. Giving, generosity, kindness, being thrifty, being prepared with disasters
D. Yes of course, that is a good deed. Common things that we can do is to share basic necessities such as foods and some money. But no matter how much we want to give, we cannot give what we do not have, so what we can do is just to treat them with kindness.
Yes, Even though we are less fortunate, it doesn’t mean that we cannot share some thing, and even though we are rich, we cannot share all things in this world. “No man is an Island.” So if we want joy in our life, we must share joy, if you want to be loved, learn to love; and if you want to be appreciated, learn to give appreciation.
For mastery, let’s now have a group. So I will group you into five.
