A1 = [a1] as a ag Ag=la, a10 all! 3 12 13 14

If (1+x)^10 = a0 + a1 x + a2 x^2 + a3 x^3 + a4 x^4 + a5 x^5 + a6 x^6 +.... a10 x^10), then the value of ( a0 - a2 + a4 - a6 + a8 -a10)^2 + (a1 - a3 + a5 -a7 + a9)^2 is :

A_1 = [a_1] , A_2=[[a_2 , a_3],[a_4 ,a_5]] , A_3=[[a_6,a_7,a_8],[a_9,a_10,a_11],[a_12,a_13,a_14]]............................A_n=[..........]where a_r=[log_2r] ([.] denotes greatest integer ) then trace of A_10

If a_1, a_2, a_3 ,........ are in A.P. such that a_1 + a_5 + a_10 + a_15 + a_20 + a_24 = 225 , then a_1 + a_2+ a_3 + ......+ a_23 +a_24 is equal to
