Assume P1(x1,x1) since OP1=1, then √x12+y12=1 x1=
1
√2
Thus, the coordinate is P1(
1
√2
,
1
√2
) If, OP2=2OP1 then, √x22+x22=1×2 x2=√2 Thus, the coordinate is P2(√2,√2) Similarly, OP3=3OP1 then, 2x32=62 x3=3√2 For, OP7 it can be expressed as, OP7=7OP1 √2x72=7×720 x7=2520√2 Thus, the coordinate is P7(2520√2,2520√2) Hence, the value of n is 7
