Takuya's parents gave him $100dollar as a birthday gift. Since he loves board games, he spent $20dollar out of his present on bo
ard games at the end of each month until his money ran out. Let f(n) be the amount of money that remained from Takuya's present during month n, where n=1 represents the month he received his present. f is a sequence. What kind of sequence is it?
p.s" tell me if it is a geometric sequence or arithmetic and find the explicit formula
To create a recursive formula, start by identifying if the sequence is geometric (for example, if the same number is being multiplied or divided for one term or more). After that, determine the common ratio (the specific number used for multiplication or division).
The simplified expression is 10m + 20.5, where m stands for the total number of months.
Initially, we can express her expenses as follows:
8.5 + 62.5m and 12 + 3.75m.
Adding these two expressions together yields a combined equation of:
10m + 20.5.
