Answer:
The correct answer is a. the value of 35 because it is not greater than 136.5
Answer:
Option 1 the given sequence is a geometric.
Step-by-step explanation:
We have been given with the series

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

here
here
We can see the difference is not same
Hence, the given sequence is not arithmetic sequence.
Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

here
here
here
We can see the ratio is same.
Hence, given sequence is geometric
Therefore, Option 1 is correct given sequence is geometric.
The sum if the geometric sequence given by:
an=-2(3)^(n-1)
will be:
when:
n=1
an=-2
when n=2
a2=-6
when n=3
a3=-18
when n=4
a4=-54
when n=5
a5=-162
when n=6
a6=-486
when n=7
a7=-1458
when n=8
a8=-4374
thus the summation of the term will be:
Sn=(-4374+-1458+-486+-162+-54+-18+-6+-2)
Sn=-6560
the answer is -6560
Answer:
k = 0.5
Step-by-step explanation:
Substitue y = 12, x = 24 into y = kx.
12 = k × 24
24k = 12
k = 12 ÷ 24
k = 0.5 (final answer)
