Look for the rules and continue these growing patterns : 2, 4, 8, 16, 32,____, _____.

The correct answer is: 64, 128

Step by step solution:
2, 4, 8, 16, 32,____, _____
the rule is to multiply the number by 2 to get the next term
2 x 2 = 4 
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 =128
Thus, the next numbers in the series are 64 and 128.
Hence, option(a) is the correct option.
