Answer 1

98+47 = 145
100+45 = 145

pattern: add 2 to 98 and subtract 2 from 47 to get the second equation (100+45)

you cannot use the pattern 97+47 because if you follow the pattern of the first equations you will not get the correct answer! You would get (99+45=144)

Answer 2

Answer Yes, because you take the answer from 100+45 and subtract 3 to get to 97 and then you add 29 to make the 47 a 74.
