Question 1 Report

The nth term of the progression $\frac{4}{2}$ , $\frac{7}{3}$ , $\frac{10}{4}$ , $\frac{13}{5}$ is ..

\frac{1 - 3 n}{n + 1}

\frac{3 n + 1}{n + 1}

\frac{3 n + 1}{n - 1}

\frac{3 n - 1}{n + 1}

Answer Details

Using Tn = $\frac{3 n + 1}{n + 1}$ ,
T1 = $\frac{3 (1) + 1}{(1) + 1} = \frac{4}{2}$
T2 = $\frac{3 (2) + 1}{(2) + 1} = \frac{7}{3}$
T3 = $\frac{3 (3) + 1}{(3) + 1} = \frac{10}{4}$
