Question

A spider caught 175 flies in her web in one week. Each day she caught 7 more flies than she did the day before. How many flies did the spider catch on each individual day?

Answer 1

Answer:

Let the spider catch x flies on the first day.

According to question, x + (x+7) + (x+14) + (x+21) + (x+28) + (x+35) + (x+42) = 175

=> 7x + 147 = 175

=> x = 4

Flies caught on each day = 4, 11, 18, 25, 32, 39, 46
