• oh dear!what's the problem?
• mom i didn't get our topic in math for today.. it's all about geometric sequence. and i dont know what geometric sequence is all about
• oh Sophie. my dear, don't be sad. mommy will teach you what is geometric sequence all about. okay?
• okay. haha, but before that let's eat first okay?
• really mom! thank you so much! you're relly the best!
• ayaye mom!
• after 2 hours..
• In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
• mom what is geometric sequence?
• 1, 2, 4, 8, 16, 32, . . . is a geometric sequence Each term of this geometric sequence is multiplied by the common ratio 2
• oh I see mother. but hehe can you give an example?
• mom what's the formula for the geometric sequence?
• ohh. I see
• If a sequence of values follows a pattern of multiplying a fixed amount (not zero) times each term to arrive at the following term, it is referred to as a geometric sequence. The number multiplied each time is constant (always the same).
• To find the common ratio, divide the second term by the first term. Notice the non-linear nature of the scatter plot of the terms of a geometric sequence.
• How do you find the common ratio of a geometric series?
