3.125 + (-3.9) - (2.46)
= 3.125 -3.9 -2.46
= -0.775 -2.46
= -3.235
Answer:
see explanation
Step-by-step explanation:
In an arithmetic sequence the common difference d is
d = a₂ - a₁ = 10 - 8 = 2
To obtain the next term in the sequence add d to the previous term, that is
a₅ = 14 + 2 = 16
a₆ = 16 + 2 = 18
a₇ = 18 + 2 = 20
The next 3 terms in the sequence are 16, 18, 20
The n th term equation for an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 2, thus
= 8 + 2(n - 1) = 8 + 2n - 2 = 2n + 6
Now, if we solve for "h", and thus put the equation in slope-intercept form,
notice what the slope is, and recall that the slope of an equation is just the "average rate of change".
I think it's 3
It should be 3 because if you have a base of 6 then your height must be 3 to get 18.
