The rule for sequence is:
Step-by-step explanation:
To write the function rule, we have to check first whether it is an arithmetic sequence or geometric sequence
So
We have to find the common difference first. Common difference is the difference between two consecutive terms of a arithmetic sequence.
So,
Here
The common difference is same so the sequence is an arithmetic sequence.
The explicit formula for an arithmetic sequence is:
Putting the values of d and a_1 we get,
Hence,
The rule for sequence is:

Answer:
i think its -14
Step-by-step explanation:
it says the temperature decreases by 6 for every 1 kilometer
if you subtract 30 from 16 (because 6 time 5 is 30)
you get -14
im not 100% sure tho
Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together
4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:
4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)
so the problem is this: 4s+12=2(s+2)
now you solved it and the answer will beeeeee s=-4
top speed of a peregrine falcon is 240 miles per hour
240 x 1/5 = 48
48-1 = 47
sailfish can swim 47 miles per hour
