Find the 5th Term 29 , 38 , 47 , 56

This is an arithmetic sequence since there is a common difference between each term. In this case, adding ${\displaystyle 9}$ to the previous term in the sequence gives the next term. In other words, ${\displaystyle a_n=a_1+d(n-1)}$.

Arithmetic Sequence: ${\displaystyle d=9}$

This is the formula of an arithmetic sequence.

Substitute in the values of ${\displaystyle a_1=29}$ and ${\displaystyle d=9}$.

Subtract ${\displaystyle 9}$ from ${\displaystyle 29}$.

Substitute in the value of ${\displaystyle n}$ to find the ${\displaystyle n}$th term.

Multiply ${\displaystyle 9}$ by ${\displaystyle 5}$.
