Write an expression to describe a rule for the sequence. Then find the 100th term in the sequence. 4, 9, 14, 19, 24, 29,...
A. 4 + 5n; 504
B. 5n - 1; 499
C. 5n; 500
D. 4n + 5; 405
A. The rule for the sequence is 4 + 5n, where n represents the nth term in the sequence. To find the 100th term, we substitute n = 99 into the expression: 4 + 5(99) = 499. Therefore, the 100th term is 499.
So the correct option is A.
