Answer:
23
Step-by-step explanation:
In arithmetic sequence, the difference between any consecutive terms is constant and the progression goes either in ascending order or in descending order.
a = first term = 2
a₂ = 5
difference = d = second term - first term
= 5 - 2
d = 3
Formula for finding nth term in arithmetic sequence:
[tex]\sf \boxed{t_n = a + (n-1)*d}[/tex]
t₈ = 2 + (8 -1) * 3
= 2 + 7 *3
= 2 + 21
t₈ = 23
