Answer:
We can write the given condition as;
Cost of digging a well for first metre = Rs.150
Cost of digging a well for first 2 metres = Rs. 150 + 50 = Rs.200
Cost of digging a well for first 3 metres = Rs. 200 + 50 = Rs.250
Cost of digging a well for first 4 metres =Rs.
250 + 50 = Rs.300
And so on..
Clearly, 150, 200, 250, 300 forms an A.P. with a common difference of 50 between each term.
