Find the First Term t_n=2n^2-n

$t_{n} = 2 n^{2} - n$

Step 1

Substitute in the value of $n$ to find the $n$ th term.

$t_{1} = 2 {(1)}^{2} - (1)$

Step 2

Simplify each term.

One to any power is one.

$t_{1} = 2 \cdot 1 - (1)$

Multiply $2$ by $1$ .

$t_{1} = 2 - (1)$

Multiply $- 1$ by $1$ .

$t_{1} = 2 - 1$

Step 3

Subtract $1$ from $2$ .

$t_{1} = 1$
