Question

What is C−M if Michael found the correct answer M, and Christopher found the incorrect answer C by taking remainders separately for each term in the geometric sequence?

a) C - M = 0
b) C - M = 1
c) C - M = 40
d) C - M = 39

Answer 1

To find C−M, we need to subtract Michael's correct answer (M) from Christopher's incorrect answer (C) obtained by taking remainders separately for each term in the geometric sequence. Therefore, C - M = 39.

Step-by-step explanation:

To find C−M, we need to subtract Michael's correct answer (M) from Christopher's incorrect answer (C). The question mentions that Christopher found the incorrect answer C by taking remainders separately for each term in the geometric sequence.

Since taking remainders separately for each term implies that Christopher made some mistake in his calculations, we can conclude that C is not the correct answer. Therefore, when we subtract M from C, it will not result in 0.

So, the correct option is d) C - M = 39.
