Find the common difference if the 8th term is 55 and the first term is 13

Step-by-step explanation:

Equation

L = a + (n - 1)*d

Givens

L = 55

a = 13

n =8

Solution

55 = 13 + (8 - 1)*d               Combine

55 = 13 + 7d                       Subtract 13 from both sides

55 - 13 = 7d

42 = 7d                               Divide by 7

d = 6

44

Step-by-step explanation:

There are the numbers which are greater than 43 and less than 52.

44, 45, 46, 47, 48, 49, 50, 51

If you add the digits the sum would be 8.

Therefore, the only number is 44, by adding digits we get 8

Answer would be 44.
