Question

Find an expression for (tn), the nth term, in each sequence.
1, 2, 3, 4, 5, ...

Answer 1

Here I am assuming you have not yet studied arithmetic progressions so I will explain it in simple terms

First term is 1
Second term is 2
Their term is 3
And so on
Hence nth term is n

By AP, 1+(n-1)1 => n
