The required sum is 2 + (−4) + (−10) + (−16) + (−22)
<h3>Sum of sequences</h3>
From the given sum of a sequence, we are to find the sum of the given sequence from n = 0 to n = 4
When n = 0
a(0) = 2 - 6(0)
a(0) = 2 - 0
a(0) = 2
When n = 1
a(1) = 2 - 6(1)
a(1) = 2 -6
a(1) = -4
When n = 2
a(2) = 2 - 6(2)
a(2) = 2 - 12
a(2) = -10
When n = 3
a(3) = 2 - 6(3)
a(3) = 2 - 18
a(3) = -16
When n = 4
a(4) = 2 - 6(4)
a(4) = 2 - 24
a(4) = -22
Hence the required sum is 2 + (−4) + (−10) + (−16) + (−22)

Answer:
1.9a
Step-by-step explanation:
6.7a - 4.8a = 1.9a
First, you need to have j on it own. Since j is over 4-8, you times both sides of the inequality so the /4-8 is canceled.
Your new inequality equation is j<4(4-8). Solve the bracket and then times the answer by 4.
~ j<4(-4)
~ j<-16
