Question

Identify the rule to find the next terms in the given pattern.
$1,2,4,8,16,\dots$

• A. Add 3
• B. Add 2
• C. Multiply 2
• D. Multiply 3

Answer 1

The correct option is C Multiply 2

The first term in the pattern is 1.
Let’s check each option one by one.
Add 3 $1,1+3=4,4+3=7\dots .$ (Doesn’t match)
Multiply 3 $1,1\times 3=3,3\times 3=9,9\times 3=27\dots$ (Doesn’t match)
Add 2 $1,1+2=3,3+2=5,5+2=7\dots$ (Doesn’t match)
Multiply 2 $1,1\times 2=2,2\times 2=4,4\times 2=8\dots$ (Matches)

So, option D is correct.
