Sequences on ACT math—need advice

Just wondering if anyone has advice for mastering sequences problems on the ACT Math section? They've been giving me some trouble lately and I'd appreciate some resources or study tips. Thank you!

Hey there! I understand how sequences could seem tricky on the ACT Math section, but with focused practice, you'll get the hang of them in no time. First off, it's important to understand the basic types of sequences you'll encounter on the test—arithmetic, geometric, and recursive sequences.

For arithmetic sequences, focus on grasping the common difference between terms and finding the general formula, An = A1 + (n-1)d. Similarly, for geometric sequences, understand the common ratio and the formula An = A1 r^(n-1). Recursive sequences are a bit different as each term in the sequence is based on one or more preceding terms.

To master these concepts, I recommend working through practice problems and watching online tutorials. Websites like Khan Academy or CollegeVine are a good starting point with their free resources. Also, consider creating flashcards with different types of sequences problems and their corresponding formulas so that you can quiz yourself regularly.

Overall, be patient and persistent. Keep practicing, and you'll see improvement in your ability to tackle sequences problems on the ACT Math section. Good luck!
