When 5 + 1 = 56, 6 + 1 = 67, 7 + 1 = 78, then 8 + 1 = ?
Answer/Solution
89
Steps/Work
5 + 1 => 5 x 1 = 5 & 5 + 1 = 6 => 5 & 6 => 56
6 + 1 => 6 x 1 = 6 & 6 + 1 = 7 => 6 & 7 => 67
7 + 1 => 7 x 1 = 7 & 7 + 1 = 8 => 7 & 8 => 78
Then 8 + 1 => 8 x 1 = 8 & 8 + 1 = 9 => 8 & 9 => 89
Answer : C
6 + 1 => 6 x 1 = 6 & 6 + 1 = 7 => 6 & 7 => 67
7 + 1 => 7 x 1 = 7 & 7 + 1 = 8 => 7 & 8 => 78
Then 8 + 1 => 8 x 1 = 8 & 8 + 1 = 9 => 8 & 9 => 89
Answer : C
