Question

Find the 50th term of the following
arithmetic sequence 5, 9, 13, 17?

Answer 1

201

Explanation:

First you need to know the position to term rule and to find this you use a formula which is:

tn = an + b

Where tn is the term number, a is the difference between the other terms.

So the tposition to term rule here is 4n+1.

Then we substitute n for the value 50 making it 4(50) + 1 = 201.

201 is the 50th term
