Answer:
1, 3, 5
Step-by-step explanation:
The sum of an arithmetic series is:
S_n = n (a_1 + a_n) / 2
100 = n (1 + 19) / 2
n = 10
The nth term of an arithmetic sequence is:
a_n = a_1 + d (n − 1)
19 = 1 + d (10 − 1)
d = 2
The common difference is 2. So the first three terms are 1, 3, and 5.
Answer:
System of Linear Equations entered :
[1] 6x-2y=8
[2] 3x-4=y
Equations Simplified or Rearranged :
[1] 6x - 2y = 8
[2] 3x - y = 4
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 3x - 4
// Plug this in for variable y in equation [1]
[1] 6x - 2•(3x-4) = 8
[1] 0 = 0 => Infinitely many solutions
