Find the 7th term in the sequence -10,-6,-2,

we are adding 4 each time

10+4 = -6

-6 + 4 = -2

-2+4 = 2

2+4 =6

6+4 = 10

10+4 = 14

14+ 4=18

The 7th term is 18

= 14

This is an arithmetic sequence with n th term

= + (n - 1)d

where d is the common difference and the fist term

d = 2 - (- 2) = - 2 - (- 6) = - 6 - (- 10) = 4 and = - 10, hence

= - 10 + (6 × 4 ) = - 10 + 24 = 14

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
