Question

Write an expression to describe the sequence. 100,200,300,400,….

Answer 1

n + 100, because you add 100 each time

n + 100, 100 + 100 = 200 and so on, making it correct

100(n), 100(100) = 10,000 which is not 200 so it’s wrong

10(n) + 10, 10(100)+10 = 1010 which is wrong

10(n) + 100, 10(100)+100 = 1100 which is wrong
