Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .

You are given the unknown number which has a quotient of 3 and a
remainder of 28. This means that 3 is the whole number from the division of the
unknown number and 43 and 28 is the decimal, 3.28. Also, the number is divided
by 43 too. Let us denote n as the number so we have n/43. Then equate the n/43
to 3.28.
n/43 = 3.28
n = 43 (3.28)
n = 141.04
