Missing value in geometric pattern

Teaching Transcript

🎙️

What term is missing in this geometric pattern?

Geometric patterns have the same ratio between all terms. We can see that every term in this pattern is 5 times the prior one.

So our missing term is 5 times smaller than 15

Which means it's 3

The skill taught is how to find a missing value in a geometric sequence by identifying the common ratio between consecutive terms and using it to calculate the missing term.
