What is the 99th term in counting by twos?

To find the 99th term in a sequence that counts by twos, we can use the formula for the nth term of an arithmetic sequence: ( a_n = a_1 + (n - 1) \cdot d ), where ( a_1 ) is the first term, ( n ) is the term number, and ( d ) is the common difference. In this case, ( a_1 = 2 ), ( d = 2 ), and ( n = 99 ). Plugging in these values: ( a_{99} = 2 + (99 - 1) \cdot 2 = 2 + 196 = 198 ). Therefore, the 99th term is 198.
