100 cm is read as 102 cm. 

A1 = (100*100)Sq.cm 

A2 = (102*102)Sq.cm

(A2 - A1) = 1022-1002 = (102 + 100) x (102 - 100) = 404 sq.cm.

Here the series follows,

194

194 - (1x1 - 1) = 194

194 - (2x2 - 1) = 191

191 - (3x3 - 1) = 183

183 - (4x4 - 1) = 168

168 - (5x5 - 1) = 144

M + Tu + W + Th = 4 x 48 = 192
Tu + W + Th + F = 4 x 46 = 184
M = 42
Tu + W + Th = 192 - 42 = 150
F = 184 – 150 = 34

The nationalisation of banks in India took place in 1969 by Mrs. Indira Gandhi the then prime minister. It nationalised 14 banks then. These banks were mostly owned by businessmen and even managed by them. Before the steps of nationalisation of Indian banks, only State Bank of India (SBI) was nationalised. It took place in July 1955 under the SBI Act of 1955.

Nationalisation of Seven State Banks of India (formed subsidiary) took place on 19th July, 1960.

1955 : Nationalisation of State Bank of India.
1969 : Nationalisation of 14 major banks.
1980 : Nationalisation of seven banks with deposits over 200 crores.

Here the given series is 1, 3, 6, 11, 20, 37, ??,

and the logic behind the series is

1 x 2 + 1 = 3

3 x 2 + 0 = 6

6 x 2 + (-1) = 11

11 x 2 + (-2) = 20

20 x 2 + (-3) = 37

37 x 2 + (-4) = 70

Hence, the next number in the given series is 70.
