To find the length of the third pregnancy required for Bengisu's average pregnancy length to equal the national average of 269 days, we first calculate the total number of days for three pregnancies at this average: 3 pregnancies * 269 days/pregnancy = 807 days. Then, we subtract the total days of the first two pregnancies from this total: 807 days - (270 days + 261 days) = 807 days - 531 days = 276 days. Therefore, Bengisu's third pregnancy must last 276 days to achieve the national average.
