Equation to find number's value:
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as .
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation:
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation , which is the same thing as the equation we were using.
Now add n and together to get .
After you do this, your equation should look like .
Now divide both sides by to get n's value.
n = 35

Answer:
The sequence is convergent and the serie is divergent.
Step-by-step explanation:
Sequence:
We calculate the limit when n tends to infinity to see if it is convergent or divergent:
then, the sequence is convergent.
Serie:
. To know if it converges we are going to use the limit test:
. If this limit is non equal to 0 the serie diverges.
, then the serie diverges.
