first term + (n-1) x common difference will give you a general rule
where the common difference between the numbers in the sequence is constant.
2.)Subtract the 1st # by 2.1, as you go up at 1 to the tenths place. Example to get to 52.3 subtract 2.1 = 50.2, to get from 50.2 to 48 Subtarct 50-2.2=48 and so on.
3.) Subtrat each one of the numbers by 1.5
4.)Add up by 5.7 then by4.8 then by 5.7
Example: 64.23+5.7=69.93,69.93+4.8=74.73,74.73=5.7=80.43, like a palendrom(575,414,232 ect.)
5.)You try # 5
Here is how you put the problems into rules above:
Simply write to procedure of what you did to slove to problems in paragraph form, like I’ve shown you above
last number + (last number – next to last number) + 1.11
