Answer 1

Answer:

Here's your answer

Step-by-step explanation:

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.
