Given the recursive formula:<br> a1=3<br> An=2(an-1+1)<br> Find a2 a3 a4

fenix001 [56]

Answer:

$a_2 = 8$

$a_3 = 18$

$a_4 = 38$

Step-by-step explanation:

We are given the following recursive formula:

$a_n = 2(a_{n-1}+1)$

And consider $a_1 = 3$

$a_2 = 2(a_1 + 1) = 2(3 + 1) = 8$

$a_3 = 2(a_2 + 1) = 2(8 + 1) = 18$

$a_4 = 2(a_3 + 1) = 2(18 + 1) = 38$

Can you help me answer this

2149 seats. Since 2149 rounds down to 2100 at the nearest hundred, this is the greatest amount of seats possible in the stadium. If there were 2150 seats, it would round to 2200 seats, so 2149 seats is the correct answer.

Hope this helps!
