the table shows the wind pressure on a structure at different heights in pa. using linear interpolation, estimate the pressure at a height of 17 ft. 6 in

the table is below:
height(ft) pressure(pa)
13 254
14 269
15 278
16 287
17 296
18 311
19 319
20 326

1. height = 13, 14, 15, 16, 17, 18, 19
pressure = 254, 269, 278, 287, 296, 311, 319, 326

2. 17'6" is halfway between 17' and 18'
So, pick a pressure value halfway between 296 and 311

That's what linear interpolation is all about.
