Find out the wrong term.
3, 2, 8, 9, 13, 22, 18, 32, 23, 42

A. 8 B. 9
C. 13 D. 22

• Answer: B 9
  There are 2 patterns in it;
  I st pattern : 3+5=8
  8+3=13
  13+5=18
  18+5=23
  II nd pattern is:
  2+10=12
  but its 9 hence its wrong
  whereas 12+10=22
  22+10=32
  32+10=42
  therefore 9 is wrong.
