1 of 1

Application +4 | -1

If the lines

x=k ; k=1,2 \ldots, n

meet the line

y=3 x+4

at the points

A_k\left(x_k, y_k\right), k=1,2, \ldots, n

then the ordinate of the centre of Mean position of the points

A_k

k=1,2, \ldots, n

View answer and explanation

Correct option: B

\frac{3 n+11}{2}

Option B (

\frac{{3 n+11}}{{2}}

) is correct because it represents the ordinate of the center of the mean position of the points

A_k

, calculated using the summation of the ordinates divided by

n
