Answer:
Any multiple of 10
Step-by-step explanation:
A factor is defined as "a number or quantity that when multiplied with another produces a given number or expression." For example, the factors of 20 are 1, 2, 4, 5, 10, and 20.
When we multiply 2 and 5 together, we get 10. Multiplying this by anything else besides 0 will still yield something that has 2 and 5 as factors, for example 2 times 5 times 3 is 30. As this is just the same thing as multiplying 10 by 3, the answer is any multiple of 10.
Answer:
A:∑j=15(2j−5)
Step-by-step explanation:
a = -3
d = -1 - (-3) = -1 + 3 = 2
j-th term: a + (j-1)d
-3 + (j - 1)(2)
-3 + 2j - 2
2j - 5
