Answer:
A) The sequence is geometric because the sequence is increasing by a factor of 2 being multiplied to each term, when ascending from left to right.
B) [tex]a_{n} = 5(2)^{n-1}[/tex]
C) [tex]a_{n} = a_{n-1} *(2) ;a_{1}= 5[/tex]
Step-by-step explanation:
The sequence is multiplying each term by a factor of 2.
5*2=10
10*2=20
20*2=40
