Arithmetic Sequence - Part 1 (MELC Quarter 1, Week 1 and 2)

Hi teachers and students!

This video is all about arithmetic sequence, its definition, illustration, derivation of the formula for the nth term (see 2:49 mark). I presented 8 examples here.

Example 1: (6:26 mark)
Given an arithmetic progression with initial term 4 and common difference 8, what is the 10th term in the arithmetic progression?

Example 2: (7:34 mark)
Given an arithmetic progression with initial term 2 and 8th term 23, what is the common difference of the arithmetic progression?

Example 3: (9:27 mark)
What is initial term in the arithmetic progression with common difference 4 and 5th term 20?

Example 4: (11:53 mark)
Given an arithmetic sequence with 35th term 15 and common difference 2, what is the 32nd term in the arithmetic sequence?

Example 5: (15:54 mark)
Given an arithmetic sequence with 11th term 12 and 15th term 40, what is the common difference of the arithmetic sequence?

Example 6: (20:06 mark)
Given an arithmetic sequence 87, 81, 75, …
a. Find the common difference of the arithmetic sequence.
b. Find the general term of the arithmetic sequence.
c. Find the smallest positive number in the arithmetic sequence.

Example 7: (23:22 mark)
Determine the value of k so that k + 2, 4k - 6 and 3k - 2 are the three consecutive terms of an arithmetic sequence.

Example 8: (25:35 mark)
The digits of a certain three-digit number form an arithmetic sequence. If their sum is 15 and the number is 119 times the hundreds digit, what is the number?

Feel free to share. Thanks!
