Question

Julian decides the price of the desserts he sells in his restaurant based on the quantity. Find which of the following rules is followed in the given pattern.

• A. Add 2
• B. Multiply by 2
• C. Divide by 2
• D. Add 4

Answer 1

The correct option is B Multiply by 2

The given sequence is 2, 4, 8, 16.

Difference between the 1st and the 2nd terms = 4 -2 = 2

Difference between the 3rd and the 2nd terms = 8 - 4 = 4

Let us find if the terms are in multiples.

First term = 2

Let us multiply it by 2, we get = 2 $\times$ 2 = 4

Second term, 4 $\times$ 2 = 8

Next term, 8 $\times$ 2 = 16

Hence, the rule followed by the pattern is, "Multiply by 2".
