Answer :
Answer:
aritmetic increases by the same number
Step-by-step explanation:
aritmetic increases by the same number
geometric has 1 number that each term is multiplied by to get the next term
4 to 9 is 5
9 to 13 is 4
not same difference
9/4=13/9?
81/36=52/36?
no
Answer:
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 =[tex]a_n - a_n_-_1[/tex]
Hence,
=[tex]a_2 - a_1[/tex]
= 9-4 = 5
= [tex]a_3 - a_2[/tex]
= 13 – 9 = 4
Since the common difference is not same
Hence it is not arithmetic
For geometric progression:
Formula used = [tex]ar^n^-^1[/tex]
Where r is the common ratio of terms= [tex]\frac{T_n}{T_n_-_1}[/tex]
=[tex]\frac{T_2}{T_1}[/tex]
= 9/4
Similarly,
= [tex]\frac{T_3}{T_2}[/tex]
=13/9
Since the common ratio is not same
Hence it is not a geometric
