What is the nth term for 7,11,15,19

Mathematics
1 answer:
Murrr4er [49]3 years ago
5 0

Answer:

a_{n} = 4n + 3

Step-by-step explanation:

Note there is a common difference d between consecutive terms, that is

d = 11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4, thus

a_{n} = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3
