STARTING TO EXPLORE 4 CONSECUTIVE NUMBERS
A) ACCORDING TO THE QUESTION, A+B+C+D=130
IF WE DIVIDE IT BY 4 BECAUSE THERE ARE 4 NUMBERS SO , 130/4= 32.5
SO IT MUST BE AROUND THAT NUMBER….
31+32+33+34=130
B) ACCORDING TO THE QUESTION,A+B+C+D=-38
IF WE DIVIDE IT BY 4 BECAUSE THERE ARE 4 NUMBERS SO, -38/4=9.5
SO IT MUST BE AROUND THAT NUMBER
-8+-9+-11+-10=-38

2) THIS QUESTION IS A TRIAL AND IMPROVEMENT METHOD…..
THE FOUR CONSECUTIVE NUMBERS ARE 5,6,7,8

3)FOR THIS QUESTION, YOU WOULD NEED TO EXPERIMENT A BIT AND FIGURE OUT SOME PATTERNS…FOR ME I GOT THAT THE NUMBER WOULD ALWAYS SUBTRACT TO THE ANSWER 0.
4)IN THIS EQUATION, THE ANSWER WOULD ALWAYS BE DOUBLE THE FIRST NUMBER, A.
