Find the 200th term of the sequence: 1, 5, 9, 13, ...

797

Step-by-step explanation:

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

d = 5 - 1 = 9 - 5 = 13 - 9 = 4

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = 4, thus

= 1 + (199 × 4) = 1 + 796 = 797
