Step-by-step explanation:
Hope this helps!!!
<span>X+(X+1)=31
</span>x is the first number and the second number should be x+1, since they are consecutive
<span>the difference between the largest and smallest data values in a data set.</span>
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)
