The first term of an arithmetic sequence is 4 and the tenth term is 67. what is the common difference? show your work or explain your answer.

Step-by-step explanation:

a1 = 4

a2 = 4 + c

a3 = 4 + 2c

a10 = 4 + 9c = 67 --> c = 7

(1, 4) ; (10, 67)

m = (y2 - y1) / (x2 - x1) = (67 - 4) / (10 - 1) = 63/9 = 7

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
