Answer:

x = 9

Step-by-step explanation:

2(x+10)+2(3x)-8 Distribute

2x+20=6x-16 Subtract like terms

20=4x-16 Add 16 on both sides since it negative

36=4x Divide 4 on both sides

x=9

What is the explicit formula for the sequence 7,2,-3,-8,-13

eduard

You could say that a(n) = 12 - 5n .

Then ...

a(1) = 12 - 5 = 7
a(2) = 12 - 10 = 2
a(3) = 12 - 15 = -3
and so on.
So it seems to work.
