the Qutb Shahi dynasty (c.1512–1687), is situated 11 km (6.8 mi) west of Hyderabad. Golkonda Fort was first built by the Kakatiyas as part of

In each number except 427, the middle digit is the sum of other two.

Numbers are 1², 2², 3², 4², 5², 6², 7².

So, the next number is 8² = 64.

Fig. (3) is formed by a combination of A-shaped elements while all other figures are formed by a combination of V-shaped elements.

Clearly,

2 x 3 = 6

6 x 3 = 18

18 x 3 = 54

So, the series is a G.P. in which a = 2, r = 3.

Therefore 8th term = ar^8-1 = ar⁷ = 2 x 3⁷ = (2 x 2187) = 4374.
