Question

Is this an arithmetic sequence? $1,8,15,22,29,..$

• A. Yes
• B. No
• C. Not a sequence

Answer 1

The correct option is A Yes

$\underset{–}{ConceptInvolved:}$

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 each successive term is obtained by adding $7$ to the previous term.

$8=1+7$
$15=8+7$
$22=15+7$
$29+22+7$

In this sequence, Next term = Previous term + Fixed Constant(i.e. $7$).
This is an arithmetic sequence.
