Question

The second term in a sequence is 13. The term to term rule is "add 6"

Answer 1

Answer:

$a_{n}$ = 6n + 1

Step-by-step explanation:

This is an arithmetic sequence with nth term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 13 - 6 = 7 and d = 6 , then

$a_{n}$ = 7 + 6(n - 1) = 7 + 6n - 6 = 6n + 1

Answer 2

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
