It would be 7.8Since 7 and 4/5ths is a mixed fraction; you would multiply 7X5= 35, then add 35+4= 39. Then you get 39/5=7.8
The answer is 12. I am 1,000,000% positive that it is the correct answer
Answer: If the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n)/2 = n [2a 1 + (n - 1)d]/2
