What is the 8th term 28, 33,38, 48

33 - 28 = 5

38 - 33 = 5

48 - 38 = 10

(5 - 5 - 10 - 10 - 20 - 20 - 40 - 40 - 80 - ...) this could be it but there are many different answers!

48 + 10 = 58

58 + 20 = 78

78 + 20 = 98

98 + 40 = 138

138 + 40 = 178

the 8th term would be 178. But again, there are many ways to solve this and there are many answers you can give!

Do you have a typo?

Besides that, is this problem a multiple choice question
