Solution
The correct option is C 24
The given sequence is 4, 8, 12.
Let us find the difference between the terms.
Difference of the 1st and the 2nd terms = 8 - 4 = 4
Difference of the 2nd and the 3rd terms = 12 - 8 = 4
To find the next term in the series, we have to add 4 to the term.
The next term in the series = 12 + 4 = 16
The consecutive terms are 20, 24.
Hence, the sixth term in the series is 24.
Therefore, the number of plants in the 6th row would be 24.
