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;498
C. 5n;500
D. 4n+5;405

Correct me
Answered by Reiny
In any of these kind of problems , n has to be a whole number, that is
n = 1,2,3, ....

My choice would be
term(n) = 5n - 1 , which is the only one that makes
term(1) = 5(1) - 1 = 4

your choice would produce a first term
of 9, which is the second term, not the first

your sequence has
a = 4, d = 5
term(100) = a + 99d
= 4 + 99(5) = 499

the correct choice has to be
term(n) = 5n-1, term(100)= 499

none of the given choices match that, unless you have a typo
notice that terms end in either 4 or 9, so 498 cannot be a term in the sequence
