a)298
b)300
c)301
d)304

Answer 1

even though i do not know the answer, i want to commend you on your decency. many students come here asking questions without being polite. i hope you get the right answer...good luck

Answer 2

a) 298
because the 100th term is the sum of
the first term, which is 1, and 99 times the common difference, whic is 3.
1+99*3= 1+297=298

Answer 3

Best way to see patterns is to write out the first few:

term, value
1, 1
2, 4
3, 7
for k = term, then value is 1+(k-1)*3, right?

Now you can just use k=100 to get the value of the 100th term...
