Answer:
10, 22, 48.4, 106.48, 234.256
Step-by-step explanation:
The first term is already given it is 10.
The second term is the first term times 2.2.
10×2.2=22
The second term is 22.
The third term is the second term times 2.2.
22×2.2=48.4
The third term is 48.4.
The fourth term is the third term times 2.2.
48.4×2.2=106.48
The fourth term is 106.48.
The fifth term is the fourth term times 2.2.
106.48×2.2=234.256
The fifth term is 234.256.

Answer:
<em>After </em><em>47</em><em> days she will have more than 90 trillion pennies.</em>
Step-by-step explanation:
At the beginning there was 1 penny. At the second day the amount of pennies under the pillow became 2.
The amount of pennies doubled each day. So the series is,

This series is in geometric progression. 
As the pennies from each of the previous days are not being stored away until more pennies magically appear so the sum of series will be,

where,
a = initial term = 1,
r = common ratio = 2,
As we have find the number of days that would elapse before she has a total of more than 90 trillion, so
