Question

find the arithmetic means in the given sequence. 175, ?, ?, ?, 235.

Answer 1

205

Answer 2

i would shift the range by subtracting 175 from all of it

0, ?, ?, ?, 60

now we need to determine 3 numbers that are evenly spaced within this range

Answer 3

60/2 = 30 for the middle

and 30/2 = 15 for the first one

30+15 = 45 for the third one

0,15,30,45,60

now add back the 175

Answer 4

i spose 60/(3+1) would have been sufficient for a common difference
