Answer:
= 6n + 1
Step-by-step explanation:
This is an arithmetic sequence with nth term
= a₁ + (n – 1)d
where a₁ is the first term and d the common difference
Here a₁ = 13 – 6 = 7 and d = 6 , then
= 7 + 6(n – 1) = 7 + 6n – 6 = 6n + 1
Answer:
the first few terms would be
7, 13, 19, 25, 31
nth term = 7 + 6(n+1)
nth term = 7+ 6n + 6
nth term = 6n + 13
