Question

( n theta )
( b )
( a r_{0} a r^{2} )
( 2 a r=a+a r^{2}-64 )
( a, a_{gamma}-8, a_{x}^{2} quad a_{p} )
( (a r-8)^{2}=left(a^{2} r^{2}-64right) a )
mos and
4,20,100 C

# Three numbers form a G.P. If the 3rd term is decreased by 64, then the three numbers thus obtained will constitute an A.P. If the second term of this A.P. is decreased by 8, a GP. will be formed again, then the numbers will be (A) 4, 20, 36 (B) 4, 12, 36 (C) 4,20, 100 (D) none of these
