<u>Answer:</u>
The type of sequence. 4,9,13,22 is neither arithmetic nor geometric
<u>Explanation:</u>
For<u> arithmetic progression:
</u>
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 <u>geometric progression:
</u>
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
