Does this explains it?
1 5 1
ok so "nth term" is the last term of every sequence
so to fin nth term you need to get the d which is the common difference and the first term which is a sub 1 and of course the last term which is the a sub n
the formula for finding the nth term is A sub n= A sub 1 +(n-1)d
Jengranger, you may explain it to your fellow students as Chryslercarl does. Bear in mind that there is a general rule (an = a1 + (n-1)d), and give example to prove your point.
thank you
