write a variabe expression to describe the rule for each sequence. then find the 100th term. 100, 200,300,400.....

To find the variable expression for the given sequence, we can observe that each term in the sequence is obtained by multiplying the position of the term by 100. Hence, the variable expression for this sequence is 100n, where 'n' represents the position of the term.

To find the 100th term, we substitute n = 100 into the variable expression:

100th term = 100(100) = 10,000

Therefore, the 100th term in this sequence is 10,000.
