Answer:
+ 3
Step-by-step explanation:
If we generate the first 3 terms using the nth term formula 3n + 2 , then
a₁ = 3(1) + 2 = 3 + 2 = 5
a₂ = 3(2) + 2 = 6 + 2 = 8
a₃ = 3(3) + 2 = 9 + 2 = 11
The first 3 terms are 5 , 8 , 11
the common difference d between the terms is
8 - 5 = 3
11 - 8 = 3
the terms go up by + 3 between each term.
