What is arithmetic progression?

Arithmetic progression is the series of number that have common difference between adjacent numbers.

Christina sold 60 vanilla cone at her first day. a=60
now each day is sells increase by 4 cones
so we common difference D = 4
The progression can be given as
S = a + (n-1)D
for 20th day = 60+(20-1)4
= 138

Thus the required number of vanilla cone she christina's sold after 20 day is 138.

Here's the answer...

2. b. 8.91, 8.9, 8.19, 8.1, 8.098
c. 20.005, 20, 19.06, 2.05, 1.905

4. a. 18.05 + 56.95

For letter a, add the whole and decimal.
18 + 56 = 74
.05 + .95 = 1

74 + 1 = 75 For letter A is 75.

b. (23.202 + 10) + (0.839 + 5.5)

Look for the parenthesis.

23.202 + 10 = 33.202
0.839 + 5.5 = 6.339

33.202 + 6.339 = 39.541 for letter B is 39.541.

c. 36 - 19.83 = 16.17 is for C

d. 1.005 - 0.2 = 0.805 is for D

e. (12.78 + 0.02) + 88

12.78 + 0.02 = 12.8

12.8 + 88 = 100.8 is for E
