Question

im working on arithmetic sequencing and im having trouble with fractions, can someone please help !

Answer 1

in an arithmetic sequence the terms increase or decrease by the same value called the common difference
its easiest to change fractions to improper type
1 3/5 = 8/5
1 1/5 = 6/5
we can write 2 as 10 /5

the common difference = 6 / 5 - 8/5 = (6 - 8) / 5 = -2/5

the 25th term is a + (25 -1)d
a = first term 2 and d = common difference -2/5

25th term = 2 + 24 * -2/5
= 10/5 - 48/5 = -38 /5 or -7 3/5

Answer 2

to change mixed fraction to improper fraction
for example

2 3/4 = (2*4 + 3) / 4 = 11 / 4

to change improper to mixed:

11 / 4 : 11 / 4 = 2 remainder 3, so its 2 3/4
