Neither.
-5 It is 15 more than -20 and 15 less than 10 To find a halfway point (which is also the average), add the numbers together and divide by 2. -20 + 10 = -10 and -10/2 = -5
The first 5 multiples of 5 are: 5, 10, 15, 20 and 25.5, 10, 15, 20, 25
5 It is 15 more than -10 and 15 less than +20. To find the halfway point (the average), add the two numbers and divide by 2. -10 + 20 = 10 divided by 2 = 5
-10
9 they are -20, -15, -10, -5, 0, 5, 10, 15, 20.
24 and 1 20 and 5 15 and 10 12, 8 and 5
20, 15, 10, 5, 0, -5, -10, -15, -20 and so on.
15-10 = 5
Sum means add them together.15+20=35
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
The first four multiples of five: 5, 10, 15, 20
-5 then add +15 -5 subtract +15=10
