Answer: Sorry mate it didn't pop up anyway hi man how's it been
For question 1, you already have that answered which is correct! for question 2, your answer would be (-2, 3)!
Equating the y's:-
3x + c = x^2 - 5x + 7
x^2 - 8x +7 - c = 0
If y = 3x + c is a tangent then there will be duplicate solutions to this equation
That is the discriminant b^2 - 4ac = 0. So we have:-
(-8)^2 - 4 * 1 * (7 -c) = 0
64 -28 + 4c = 0
4c = - 36
so c = -9 answer
Do you have question choices if not then I'll try I guess......
-27+9-3+1
36-3+1

Answer:
105th term of given series is

Step-by-step explanation:
Given series is

As we can see,

Also,

hence, we can say given series is in arithmetic progression,
with common difference,

As given in question the nth term in A.P is given by

since we have to find the 105th term, so we can write



Hence, the 105th term of given series of A.P is
.
