Answer 2

Step-by-step explanation:

Given series is -

452-432 + 442 - 422 + 432 - 413 422

40.. to 30 terms.

.First term is 45

Second term is 2 less than first term that

is 45 2 43

So, Second terms is 43

next term is one more than previous term

that is 43+1 44

.Third term = 442

Sign change alternate +, ,t,.

Now we follow the same pattern

Series is:

452-432 + 442-422 +432-412 422

402+ 41-392+402- 382+392... 30

= 452+442 303

2025 + 1936 900

3061

Sum of the series = 3061
