Solution :
First term, a₀ = -10 .
Common difference of A.P. , d = -8 - (-10) = 2 .
Last term, aₙ = 24 .
We know, last term is given by :
aₙ = a₀ + (n-1)d
24 = -10 + (n-1)×2
2n - 2 = 34
n = 18
Now, sum of series is given by :
Hence, this is the required solution.
Answer:
Step-by-step explanation:
<u>Given the system of equations</u>
<u>Divide 3 on both sides of the 2) equation</u>
<u>Current system</u>
<u>Substitute 1) equation into the 2) equation</u>
<u>Combine like terms</u>
<u>Subtract 15 on both sides</u>
<u>Divide 4 on both sides</u>
<u>Substitute the x value into one of the equations to find the y value</u>
