Q1. a repeat 1,b-2,c-3,d-4 ,
use 1(a)+2(b,b)+3(c,c,c) ….=n(n+1)/2 =288
find n.(by hit and trail like n=23, the (23X24)/2=276 and proceed, ex- 28th(a.b,b,c,c,c… term is last of 7th(1+2+3+4+5+6+7(g)+..
276this the end of23th term, so 24th term is X. since X repeat 24 times so 288th is X

Sir can u plz send me the solution of question 1,6,9.it will be a very kind help.

answer to question no. 9 is D(i.e none).

Q1. a repeat 1,b-2,c-3,d-4 ,

use 1(a)+2(b,b)+3(c,c,c) ….=n(n+1)/2 =288

find n.(by hit and trail like n=23, the (23X24)/2=276 and proceed, ex- 28th(a.b,b,c,c,c… term is last of 7th(1+2+3+4+5+6+7(g)+..

276this the end of23th term, so 24th term is X. since X repeat 24 times so 288th is X
