Final answer:
The 28th term of the sequence is 773.
Step-by-step explanation:
To find the 28th term of the sequence, we need to analyze the pattern. Looking at the sequence, we can see that the terms are increasing by a constant difference: first term to second term is an increase of 31, second term to third term is an increase of 422, and so on.
So, we can find the common difference by subtracting the second term from the first term: -33 - (-64) = 31.
Now, we can find the 28th term by adding the common difference to the first term 27 times: -64 + 31(27) = -64 + 837 = 773.
