The cost of borrowing achievable 600 is as follows 25 paisa for the first metre and an additional for pressure for every subsequent metres find the cost of borrowing of 500 metre long tube well and also the total cost

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

b, i believe, but not sure.

i don’t see a picture
