Question

Danica read 40 pages of her book on Monday, 37 pages on Tuesday, 34 pages on Wednesday. She continued this pattern until she finished the book. What was the total number of pages she read in 1 week?



Select one:
a. 164
b. 205
c. 186
d. 174

Answer 1

Explanation

the pattern which is being followed is that she always reads 3 pages less than the day before so-

40(Monday)-3=37(Wednesday)

Number of days in a week=7

Monday-40

Tuesday-37

Wednesday-34

Thursday-31 (34-3)

Friday-28(31-3)

Saturday-25(28-3)

Sunday-22 (25-3)

Therefore 40+37+34+31+28+25+22=217

Step-by-step explanation:

She read a total of 217 pages in the first week
