Answer:

a(n) = 10n-1 (the second one)

Step-by-step explanation:

we use formula

a(n) = a +(n-1)d (a= the first number in the, n=the times we need, d= difference)

a=9

d=9-19=10

a(n) = 9 +(n-1)10

a(n) = 9 +10n-10

a(n) = 10n-1 (the second one)

I hope it will help

$\text{Hey there!}$

$\text{In order for you to solve for this equation, you need to distribute.}$

$\text{The formula is: a(b + c) = a(b) + a(c) = ab + ac}$

$\text{Keep that method in mind.}$

$\text{4(x + 7)}\\\\\text{4(x) + 4(7)}\\\\\text{4(x) = 4x}\\\\\ 4(7) = 28\\\\\boxed{\boxed{\text{\bf{Answer: 4x + 28}}}}\bf\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
