Write arithmetic sequence with recursive formula numbers 94,81,68, 55

f(n) = f(n - 1) - 13

Steps:

The given sequence is 94, 81, 68, 55, …

We can observe that the common difference between two consecitive terms is 13 since 94 - 81 = 13

Since f(1) = 94, and the form of a recursive formula is f(n) = f(n - 1) + d, we just have to plug in d = -13 in order to get f(n) = f(n - 1) - 13.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
