Answer:262 days

Step-by-step explanation:

Pregnancy 1=270 days

Pregnancy 2= 260days

Pregnancy 3=272 days

To find cumulative days for all four pregnancies to equal an average of 266days

For the average to be 266 days

266×4=1064

Sum of all 3 pregnancies = 270+260+272=802

Sum of all cumulative days for all four pregnancies-sum of the three pregnancies

1064-802=262

So for the average to be 266days

The forth pregnancy has to

262 days

266 * 4 = 1064 days. The total days she’s been pregnant is the sum of those 3 pregnancies which is 802 days. Therefore, she needs her pregnancy to be 262 days to equal the average.
