Video Animasi Matematika | Barisan Aritmatika

Assalamualaikum warahmatullahi wabarakatuh Hello everyone, meet again with me, Jose Abdallah Here we will learn about arithmetic What is arithmetic? Does anyone know? Let's discuss together

There is a child named Ali. He really likes to plant. One day, Ali started planting trees and was well taken care of. Every day, Ali always watered and gave kukuh to his plants, so every week Ali always observed the growth rate of his plants. On the first week, the plant grew and had a height of 3 cm.

For the second week, the plant increased in height to 8 cm. Because it grows well, on the third week the plant increased in height to 13 cm. Ali plans to harvest the plant on the 12th week. So, can you count how many plants are there on the 12th week? Anyone know? Let's discuss together.

Now let's pay attention to the height increase of the plant from week 1 to week 2 is 5 cm. Likewise, from week 2 to week 3 is the same 5 cm.

Likewise, for the next week's growth, we assume the same growth, which is 5 cm. So, every week the plant has a growth height of 5 cm. Here is an arithmetic line. So what is the arithmetic line?

So the arithmetic line is the number line that each order of its axis has a difference or the same error. From the problem of the plant growth earlier, we can change it into the form of the arithmetic number line, such as 3, 8, 13, 18, and so on, with a constant difference, namely 5.

The formula for the n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-n-

Now, try to pay attention again. We know the first axis or A is 3 cm, the second axis is 8 cm, the third axis is 13 cm, and the difference between the axes is 5 cm. So, the 12th axis is U12 = A = 3 + N = 12 - 1 * B = 5.

U12 = 3 + 11 x 5 = U12 = 3 + 55 = 58

So, in conclusion, the height of the Ali plant on the 12th week is 58 cm. That's my video, I'm sorry. Thank you for watching. I hope this video is useful for all of you.
