0,7,14,21 What is the next number? What is the 1000th term? We're adding 7 to the last term, so we get a next term of: 21 + 7 = 28 For our nth term, we notice a pattern for the nth term of: 7n - 7 n = 1 --> 7(1) - 7 = 0 n = 2 --> 7(2) - 7 = 7 n = 3 --> 7(3) - 7 = 14 For n = 1000, we have: 7(1000) - 7 = 7000 - 7 = 6993
