# Nineteenth member

Find the nineteenth member of the arithmetic sequence:

a1=33
d=5
find a19

Result

a19 =  123

#### Solution:

$a_{1}=33 \ \\ d=5 \ \\ n=19 \ \\ \ \\ a_{19}=a_{1} + (n-1) \cdot \ d=33 + (19-1) \cdot \ 5=123$

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
