What's the answer for 4d - 35= -3

Ket [755]

Answer:

The answer is <u>8</u>.

Step-by-step explanation:

Given:

4d - 35= -3.

Now, the solution:

$4d-35=-3$

Adding both sides by 35 we get:

$4d=-3+35$

$4d=32$

Dividing both sides by 4 we get:

$d=8$

Therefore, the answer is 8.

The sum of the first n terms of an arithmetic sequence is n/2(4n + 20).

lesantik [10]

Answer:

(a).

$S_{n} = \frac{n}{2} (4n + 20) \\ \\S _{n - 1} = \frac{(n - 1)}{2} (4n - 4 + 20) \\ \\ S _{n - 1} = \frac{(n - 1)}{2} (4n + 16) \\ \\S _{n - 1} = \frac{(n - 1)(4n + 16)}{2} \\ \\ { \boxed{S _{n - 1} = {2 {n}^{2} + 6n - 8}}} \\$

(b).

from general equation:

$S _{n - 1} = \frac{(n - 1)}{2} (4n + 16)$

first term is 4n

common difference:

$16 = \{(n - 1) - 1 \}d \\ 16 = (n - 2)d \\ d = \frac{16}{n - 2}$
