|
Answer» P{a} is also known as subset so {1},{2}, {3},{1,2},{2,3},{3,1},{1,2,3},¢, total 8 4) Here we get a=4 ,d=5 and Sn=254As we know,Sn=n/2[2a+(n-1)d]254=n/2[8+5n-5]508=n[5n+3]508=5n^2+3n5n^2+3n-508=0 Now further you do it yourself.. Find the centre and radius of the circle xsqure +ysqure - 8x-4y-5 =0 Find the coordinates of the point that trisect the line segment joining the points (1,-2,7)&(4,1,-5) Which term of the series 4 +9+14+........is254 |
