❦︎The cost of digging a well after every metre of digging, when it costs Rs 150 for the first metre and rises by Rs 50 for each subsequent metre❦︎??​

Answer 1

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.
