The closed formula for <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)
</span>
Answer: 36f/6f-1
solution: move all terms to left side and set equal to zero. then set each factor equal to zero.
A prediction that suggests what you expect will happened is called a Conjecture.
It is different from probability.
Answer:
36.92 but rounded it up its 37
Step-by-step explanation:
Solution for 7.2 is what percent of 19.5:
7.2:19.5*100 =
(7.2*100):19.5 =
720:19.5 = 36.923076923077
Now we have: 7.2 is what percent of 19.5 = 36.923076923077
