A) Yes. we don't have enough information so this can not be determined.
B) No, it would just be an outlier.
1995 = x
1996 = x + 0.62
1997 = x + 0.62 + 0.29
x + x + 0.62 + x + 0.62 + 0.29 = 11.25
3x + 1.53 = 11.25
3x = 11.25 - 1.53
3x = 9.72
x = 9.72 / 3
x = 3.24 <== 1995 = 3.24 million
1996 = 3.24 + 0.62 = 3.86 million <==
1997 = 3.24 + 0.62 + 0.29 = 4.15 million <==
Seven hours and 5 minutes
IO/2.4 = I5/x
IOx = 36
x = 3.6
