note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

, and for

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
