Hard
Three of the following four letter groups are alike in a certain way and one is different. Find the different one: AZBY, CXDW, EVFU, HSGT
Explanation
Explanation
In AZBY, CXDW and EVFU, the letters follow the order (small, big, small+1, big-1), e.g. A,Z,B,Y. In HSGT, the same four letters appear (G,H,S,T) but in a scrambled order that breaks this small-big-small-big pattern, so HSGT is the odd one out.
PRO TIP
Re-check your working by substituting the answer back into the original question.
