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
To find the answer of this problem you need the formula for a cylinder.
V= pi* r^2 * h just plug in your numbers and you have the answer.
You also need to remember that diameter is just twice the radius.
Answer:
75
Step-by-step explanation:
If the third of 6 consecutive numbers is 12, what is their sum?
6 numbers = c-2, c-1, c, c+1, c+2, and c+3
The numbers become 10, 11, 12, 13, 14, and 15
Add that together and you get 75.
