How do i find the nth sequence in this sequen 7cm 10cm 13cm 16cm

= 3n + 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence

10 - 7 = 13 - 10 = 16 - 13 = 3

This indicates the sequence is arithmetic with nth term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 3 , then

= 7 + 3(n - 1) = 7 + 3n - 3 = 3n + 4

y= -5 x=3

Step-by-step explanation:

x=y+8

4x+2y=2

4(y+8)+2y=2

4y+32+2y=2

6y+32=2

6y+32-32=2-32

6y=-30

6y divided by 6 = -30 divided by 6

y=-5

4x+2y=2

4x+2(-5)=2

4x-10=2

4x-10+10=2+10

4x=12

4x divided by 4 = 12 divided by 4

x= 3
