a) 8
b) 5
c) 2
d) 13

Explanation: Here, the series is a Fibonacci series.
i.e., a number in the series is the sum of previous two numbers.
So, in this 0+1 = 1. So the wrong number is 2.

3. Find the next number in the series: 7, 63, 215, 511, …. ?
a) 824
b) 728
c) 999
d) 693

Explanation: Here, each number is one less than cube of a number.
i.e. 23=8-1=7, 43=64-1=63, 63=216-1=215, 83=512-1=511.
So, the next number will be 103=1000-1=999.
