Can the sum of two mixed numbers be equal to 2? explain

What is the size of the matrix resulting from

Use the ratio test to determine whether ∑n=14∞n+2n! converges or diverges. (a) find the ratio of successive terms. write your answer as a fully simplified fraction. for n≥14, limn→∞∣∣∣an+1an∣∣∣=limn→∞.

Twice the sum of a number and 2 is equal to three times the difference of the number and 8. find the number.
