Answer:

Step-by-step explanation:
The sum of the first 10 terms of an arithmetic sequence is:


the sum of the second 10 terms is: a₁₁ + a₁₂+...+ a₂₀
And the sum of the first 20 terms of an arithmetic sequence is:

so the sum of the second 10 terms is:
Therefore we have:

and:

For the answer to the question above, I think since there are only two numbers in the given sequence that are even or greater than 78. I think the probability would be <u><em>0.4 </em></u>
I hope this helps you somehow. Have a nice day!

Hope I helped :)
I think if you do 9.00 + 9.00 to get 18.00 then do 17.00 + 17.00 to get 34.00 then do 41.00 + 41.00 to get 82.00 your answer will be 18.00+34.00+82.00= 134 so that’s your answer. Pls make me the brainliest
