n indicates the number of terms, or a term in a particular position.

n a;ways starts from 1.

So we need to use n=1,n=2,n=3 etc

${a}_{1}=3\left(1\right)+1=4$
${a}_{2}=3\left(2\right)+1=7$
${a}_{3}=3\left(3\right)+1=10$

But by this term we can see that each term is 3 more than the previous :

13,16,19

For an AP, the coefficient of the n term also indicates d.
