Check your answer:-
similarly before 8th temple: (300+100)*2 + 100 = 900
similarly before 7th temple: (900+100)*2 + 100 = 2100
similarly before 6th temple: (2100+100)*2 + 100 = 4500, we had some error here in calculating, thanks to our readers for correcting us
similarly before 5th temple: (4500+100)*2 + 100 = 9300
similarly before 4th temple: (9300+100)*2 + 100 = 18900
similarly before 3rd temple: (18900+100)*2 + 100 = 38,100
similarly before 2nd temple: (38100+100)*2 + 100 = 76500
similarly before 1st temple: (76500+100)*2 + 100 = 153300

Actually this is a GP with first element as 1 and variable factor. where the factor comes from this series
1, 3, 7, 13.
Tn = Tn-1 + 2^(n-1);
T1 = 1;
T2 = T1 + 2^(2-1)= 1 + 2 = 3;
T3 = T2 + 2^(3-1) = 3 + 4 = 7;
T4 = T3 + 2^(4-1) = 7 + 6 = 13
nth number in GP = first number * (10)(Tn-1 in series);
First Element in GP = 1;
Second Element in GP(i.e. n = 2) = 1*10*(T1 in series); = 10
Third element in GP(i.e. n =3) = 1*10*(T2 in series) = 1*10*3 = 30
Fourth element in GP (i.e. n =4) = 1*10*(T3 in series) = 1*10*7 = 70
Fifth element in GP (i.e. n =5) = 1*10*(T4 in series) = 1*10*13 = 130
Thus the missing number here is 70.
