Answer:

No 108 is not a term of this sequence.

Step-by-step explanation:

3n+5 = 108

3n = 108 - 5

3n = 103

Divide both side with 3.

n = 103/3

n = 34.33

since n is not equal to 108 there it is not

Answer:

see below

Step-by-step explanation:

We can determine if 108 is a solution by setting 3n+5 =108

3n+5= 108

Subtract 5 from each side

3n+5-5=108-5

3n = 103

Divide by 3

3n/3 = 103/3

n = 103/3

This is not an integer so 108 is not a solutions
