Answer: It dosn't show anything for me. did you post it?
Ok so
The answer would be the second one (3+3+3+3=3 (4) )
Here's the explanation
It doesn't belong there because all the rest have to do with exponents
And that problem does not
Also,that problem uses repetitive addition while the other ones use repetitive multiplication
Hope this helps :)
Subtract each terms.
2.7 - 1.5 = 1.2
3.9 - 2.7 = 1.2
From these, we can see that they add 1.2 each time. 8.7 is the last number, so each numbers in the sequence is.
1.5, 2.7, 3.9, 5.1, 6.3, 7.5, 8.7
Add all of these numbers together.
1.5 + 2.7 + 3.9 + 5.1 + 6.3 + 7.5 + 8.7 = 35.7
35.7 is your answer
hope this helps
