Question

Is this sequence an arithmetic sequence? $2,8,5,11,8,14,...$

• A. No
• B. Yes
• C. Not a sequence

Answer 1

The correct option is A No

$\underset{–}{ConceptInvolved:}$

When the successive term in a numerical pattern is formed by adding a fixed constant value to the previous term, the sequence obtained is an arithmetic sequence.

$\underset{–}{Method:}$
Here next term is not obtained by adding a "fixed constant value" to the previous term.

$2+6=8$
$8-3=5$
$5+6=11$
$11-3=8$
$8+6=14$

This is a sequence but not an arithmetic sequence since a fixed constant value is not added to previous term to obtain next term.
