value

if you start with 3 and count by 7s, you get the terms of the sequence 3,10,17...528 wheere 3 is he 1st term,10 is the 2nd term,17 is the 3rd term,and so forth up to 528 which is the Nth term. What is the value?

3+(n*7) = 528
-3 -3
n*7=525
divide by 7
525/7=75

You could have also used a calculator adding 7 to 10 til you got to 525 and counted. It would have been tedious but it would have worked.
