N2 2 = 0+(20n1 -19) n+ (2n-2) n



2

N2 2 = 100+(20n1 -19) n+ (2n-2) n



2



N2 2 = 400+(20n1 -19) n+ (2n-2) n



2



N2 2 = 900+(20n1 -19) n+ (2n-2) n



2





For Example



(1) 222 = 400 +(22 * 3 -19) 2+ (2*2-2)/2)2

= 400 +(60 -19)2 +((4-2)/2)2

=400 +(41*2)+(2/2)2

=400 +82 +2

=400+84

=484



(2) 112 = 100 +(20 * 2 -19) 1+ (2*1-2)/2)2

= 100 +40 -19 +0

=100 +21

=121





Note : n1=2 and n2=11

(3) 252 = 400 +(20 * 3 -19) 5+ ((2*5-2)/2)5

= 400 +(60 -19 )5+20

=400 +41*5+20

=420+205

=625



(4) 92 = 0 +(20 n 1 -19) n+ ((2 n-2)/2)n

= 0+(20 * 10 -19)9+ ((2* 9 -2)/2)9

=0+(200-19)9+(16/2)9

=0+(



(5) 112 = 100 +(20 * 2 -19) 1+ (2*1-2)/2)2

= 100 +40 -19 +0

=100 +21

=121
