Sequences are great but they can be very challenging at times. There are several formulas to learn and different types of sequences. There are geometric and arithmetic. There can also be infinite solutions. But, if you stick to the formulas and plug in the right numbers you can't go wrong. For arithmetic sequences. Here are the formulas:
Thank you for posting all the formulas! This tells me what each formula can find for me. Thanks for putting examples under the formulas this helps me understand the formulas much better. This will help me when I study for the test. Thanks again!
