Explanation:

a1 = 81.33
a2 = –19
a3a2 ​​​​​​​- a1 = –100.33
a4a3 ​​​​​​​- a2 ​​​​​​​ = –81.33
a5a4 ​​​​​​​- a3 ​​​​​​​ = 19
a6a5 ​​​​​​​- a4 ​​​​​​​ = 100.33
a7a2 ​​​​​​​- a5 ​​​​​​​ = 81.33
a8a7 ​​​​​​​- a6 = –19

We can see that the sequence repeats itself after every 6 terms.

Sum of the first 6 terms of the sequence = 0

Thus, the sum of the first 6000 terms of this sequence = 0

The sum of the 6001st and 6002nd terms = 81.33 – 19 = 62.33

Hence, option (c).
