Answer:
Glenn is correct.Andy multiplied 675 by 2 two times.
Step-by-step explanation:
We are given that Andy multiplied 675 times 22 and got=2700
Glenn multiplied 675 by 22 and got=14850
We have to find the student which is correct and find the mistake of other student.
When 675 multiplied by 22
Then ,
Therefore, correct answer is 14,850.
Hence, Glenn is correct.
Therefore, Andy makes mistake in calculation. .Andy did multiplied 675 by 2 two times .
Answer:
Step-by-step explanation:
we know that
The rule to calculate the an term in an arithmetic sequence is
where
d is the common difference
a_1 is the first term
we have that
so
The common difference is d=5
Find 60th term of the sequence
we have
substitute
Answer:
an = 65 + 5
a1 = 65
Step-by-step explanation:
If the begining value is 65, then a1 has to be itL
a1 = 65
Then, if this amount increased every minute then 5 has to be added to this value each time:
an = 65 + 5
But this means that 5 is added to 65 every time with no increase, so the five must me multiplied by the n value:
an = 65 + 5
a2 = 65 + 10 = 75
But this value should be 70 because it is the first point after 65 so it should be +5 not +10
To do this we can simply subtract one from the n value that is being multiplied by 5:
an = 65 + 5
Which is the recursive rule!
