~~i raised the points and will give brainliest its also multiple choice~~
which describes the type of sequence in 99, 89.9, 78.8, 68.7, . . . ?
a) neither geometric nor arithmetic
b) geometric
c) arithmetic
d) both arithmetic and geometric
( tell me why you picked your answer)

Option 'a' is correct.

Step-by-step explanation:

Since we have given that

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

Here,

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.

Their difference are not common.

So, It is neither geometric nor arithmetic.

Hence, Option 'a' is correct.

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
