What answer describes the type of sequence. 4,9,13,22

neither arithmetic nor geometric

geometric

arithmetic

The type of sequence. 4,9,13,22 is neither arithmetic nor geometric

Explanation:

For arithmetic progression:

Formula used  = a +(n-1)d

Where d is the difference of numbers in the sequence =

Hence,

=

= 9-4 = 5

=

= 13 – 9 = 4

Since  the common difference is not same

Hence it is not arithmetic  

For geometric progression:

Formula used =

Where r is the common ratio of terms=

=

= 9/4

Similarly,

=

=13/9

Since the common ratio is not same  

Hence it is not a geometric
