Question

Choose the correct statement(s):

$A$: Every sequence is a progression.

$B$: Every progression is a sequence.

• A. Only $A$
• B. Only $B$
• C. Both $A$ and $B$
• D. None

Answer 1

Answer: (B)

Only $B$

The difference between a progression and a sequence is that a progression has a specific rule to calculate its next term from its previous term, whereas a sequence can be based on a logical rule like 'a group of prime numbers'.

Thus, every progression is a sequence but every sequence is not a sequence.
