How to determine if a sequence is arithmetic or geometric

The video tutorial reviews arithmetic and geometric sequences, explaining how to identify each type. Arithmetic sequences have a constant difference between terms, while geometric sequences have a constant ratio. The tutorial provides examples to illustrate how to determine the type of sequence by checking differences and ratios.

Explain the significance of the terms 'difference' and 'ratio' in the context of sequences.

What is the process to check if a sequence is neither arithmetic nor geometric?
