The series follows a pattern where each number is obtained by adding 8 to the previous number. Starting from 8, adding 8 gives us 16, then adding 8 again gives us 24. Continuing this pattern, the next number would be obtained by adding 8 to 24, which gives us 32.

Explanation
The pattern in the series is that every alternate number is obtained by adding 2 to the previous number, while the other numbers are obtained by adding 4 to the previous number. Starting with 4, we add 2 to get 6, then add 4 to get 10, then add 2 to get 12, then add 4 to get 16. Therefore, the next number in the series would be obtained by adding 2 to 16, resulting in 18.

### One carrot is consumed by Rico the Rabbit on Sunday, two on Monday, four on Tuesday, and so forth. He consumes how many carrots per week?

• A.

127 carrots

• B.

120 carrots

• C.

117 carrots

• D.

115 carrots

A. 127 carrots
Explanation
Rico the Rabbit consumes 1 carrot on Sunday, 2 on Monday, 4 on Tuesday, and so on. This is an example of a geometric sequence, where each term is double the previous term. To find the total number of carrots consumed per week, we need to sum the terms of this sequence. The sum of a geometric sequence can be calculated using the formula Sn = a(1 - r^n) / (1 - r), where a is the first term, r is the common ratio, and n is the number of terms. In this case, a = 1, r = 2, and n = 7 (since there are 7 days in a week). Plugging in these values, we get Sn = 1(1 - 2^7) / (1 - 2) = 1(1 - 128) / (-1) = -127 / (-1) = 127. Therefore, Rico consumes 127 carrots per week.
