Omg this is so confusing does this look correct 2 u guys? plz help if ur good at math

I'm sure the actual answer is ( B )

So 4, 9, 14, 19, ... ?

For ( B ) Why not try substitute n = 1 and look for the value of n itself?

So we substitute all inputs (n = 1, 2, 3 and 4) then the outputs should be (4,9,14,19) in order.

You notice that whenever I substitute n = 1,2,3,4. I get the exact outputs that are given.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
