Answer:
the sequence is geometric sequence with common ratio (-2).
Option : D is correct.
Step-by-step explanation:
In this question table is given as
n 1 2 3 4 5
f(n) 48 -96 192 -385 768
We have to find out if the sequence is arithmetic or geometric.
For Arithmetic sequence :
Difference should be common in each term of fees.
common difference = f(2) - f(1)
= -96 -48 = -144
similarly = f(3) - f (2) = 192 + 96 = 288
Here, ≠ so the sequence is not an arithmetic sequence.
For Geometric sequence :
Ratio should be common in each term of f(n)
Common ratio =
Therefore, the sequence is geometric sequence with common ratio (-2).
Option : D is correct.
7*40 = 280, 7*2 = 14,
add both and get 280+14 = 294
Answer:
v=-7
Step-by-step explanation:
2(v-8)-8v=26
2v-16-8v=26
-6v-16=26
+16 +16
-6v=42/-6
v=-7
