The ${288}^{th}$ trem of the series $a,b,b,c,c,c,d,d,d,d,e,e,e,e,e,f,f,f,f,f,f$,....., is

• A. $u$
• B. $v$
• C. $x$
• D. $w$

Answer 1

The correct option is C $x$

The alphabet is repeated as many times as its value, i.e. a is repeated once.

nth digit will be given by sum of natural numbers formula.

$a=288<\frac{n(n+1)}{2},n=23,a=276,n=24,a=300,n=24$ the alphabet is $x$
