Answer and step-by-step explanation:
The given arithmetic sequence are finite and there are no missing terms so you can find the sum of the terms by simply adding all of them together.
1) 5, 10, 15, 20, 25
5 + 10 + 15 + 20 + 25
= 75
2) 2, 6, 10, 14, 18
2 + 6 + 10 + 14 + 18
= 50
3) 2, -3, -8, -13, -18
*Put parentheses on the negative integers to avoid confusion when solving the problem.
2 + (-3) + (-8) + (-13) + (-18)
= -40
4) -1, -5, -9, -13, -17
(-1) + (-5) + (-9) + (-13) + (-17)
= -45
5) 120, 115, 110, 105, 100
120 + 115 + 110 + 105 + 100
= 550
