Solve for n.
2-1/2n = 3n+16

n=-4

Step-by-step explanation:

See the steps below:)

n = -4

Step-by-step explanation:

We want to solve for n, so let's get n on one side of the equation.

Add to both sides.

2 = 3.5n + 16

Subtract 16 from both sides.

-14 = 3.5n

Divide both sides by 3.5

-4 = n

Check your answer by plugging n back into the original equation.

Multiply.

2 + 2 = -12 + 16

Add.

4 = 4

Your answer is correct.

Hope this helps!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

x=half
