-3. - 1.1.3.5.7.9. What is the general formula of sequence?

This is an arithmetic sequence whose first term is - 3
So an = - 3 + 2 (n-1) = 2n-5

A general term formula for sequence 1 / 5.3/10,1 / 3,7 / 20,9 / 25

an=(2n-1)/5n
1 / 3 is 5 / 15, you can see by yourself

The formula for finding the general term of the sequence

(2+5)/2=3.5
(5-2)/2=1.5
So an = 1.5 * (- 1) ^ n + 3.5
If you don't understand, I wish you a happy study!
