Answer:

a) Neither arithmetic nor Geometric

Explanation:

Since 99-89.9= 9.1, and 89.9 - 78.8 = 11.1, the sequence is not arithmetic.

Like wise 89.9/99=0.908 and  78.8/89.9 = 0.876 makes it not a geomtric sequence

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

99, 89.9, 78.8, 68.7, . . . . .

Here,

a_1=99\\\\a_2=89.9\\\\a_3=78.8\\\\a_4=68.7

But we can see that there is minor difference between the consecutive terms:

So, we will go for common difference whether it is same or not.

a_2-a_1=89.9-99=-9.1\\\\a_3=a_2=78.8-89.9=-11.1\\\\a_4-a_5=68.7-78.8=-10.1

Their difference are not common.

So, It is neither geometric nor arithmetic.

Hence, Option 'a' is correct.

Deductive reasoning

Step-by-step explanation:

Here, we want to know the kind of reasoning the statement is.

In this question, the kind of reasoning is deductive

In the deductive reasoning type, we go from general cases to specific cases

It is just like saying the reason why there will be hurricanes in the tropics this fall is because there is an hurricane every fall

If a+ b + c= -6 and x +y = 5, what is 9y +9x - 10a-10c -10b ?
Lisa [10]

Answer:

9y +9x - 10a-10c -10b = 105

Step-by-step explanation:

Given

a+b+c = -6 and x+y = 5

We have to find 9y +9x - 10a-10c -10b

Rearranging the terms

9x+9y-10a-10b-10c

Simplifying will give us:

= 9 (x+y) - 10(a+b+c)

Putting the values of x+y and a+b+c

= 9(5) -10(-6)

=45+60

=105

Therefore,

9y +9x - 10a-10c -10b = 105 ..
