The sequence an = 8, 13, 18, 23, ... is the same as the sequence a1 = 8, an = an-1 + 5.

Actually, this answer would be true. Why?

The first equation is: a(sub <em>n</em>) = 8, 13, 18, 23

The second is: a(sub 1)=8 ; a(sub <em>n</em>)= a(sub <em>n</em>-1)+5
if you wish to find the second term, plug two into the equation for <em /><em>n</em>
8+5=13
to find the third, plug the second term, 13, in for <em>n.</em>
13+5=18.

Hope this helped! I know it's a bit on the late side, but at least you can get the general idea!

Maria bought 5 tickets for $20 each. Each ticket had a $2 fee. Write an expression that shows how much Maria paid for the ticket

Tanya [424]

The algebraic expression which shows how much Maria paid for the tickets including the additional fee is y = 20(5) + 2(5)

<h3>Algebraic expression to show how much Maria paid for the tickets</h3><h3 />

Number of tickets Maria bought = 5
Cost of each tickets = $20
Additional fee per tickets = $2

let

Total amount Maria paid for the tickets = y

Total amount Maria paid for the tickets = Cost of each tickets(Number of tickets Maria bought) + Additional fee per tickets(Number of tickets Maria bought)

y = 20(5) + 2(5)

y = 100 + 10

y = $110

Therefore, the algebraic expression which shows how much Maria paid for the tickets including the additional fee is y = 20(5) + 2(5)
