Question

4. How many terms of the series 64 + 32 + 16 + ... ... must be taken so

that the sum may be 255÷2​

Answer 1

... ... = .5

Explanation:

I'm not sure if I'm right. But I got my answer by dividing 255 and 2 first

255 / 2 = 112.5

Then find out what 64 + 32 + 16.

64 + 32 + 16 = 112

Add 0.5 to get the same answer from 255 / 2

64 + 32 + 16 + 0.5 = 112.5
