1)Determine whether the sequence could be arithmetic. If so, find the first difference and the next term. -1,-4, -7, -10, -13,... d = a6 =​

x= 149. 24+7=31. 180-31=149

your welcome

give more details

step-by-step explanation:

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

step-by-step explanation:

the correct answer is 5 6 and 7
