Solve a_{1}=1+1/2(1)

$$a _ { 1 } = 1 + \frac { 1 } { 2 } ( 1 )$$

Solve for a_1

$$a_{1} = \frac{3}{2} = 1\frac{1}{2} = 1.5$$

Steps for Solving Linear Equation

Multiply \frac{1}{2} and 1 to get \frac{1}{2}.

$$a_{1}=1+\frac{1}{2}$$

Convert 1 to fraction \frac{2}{2}.

$$a_{1}=\frac{2}{2}+\frac{1}{2}$$

Since \frac{2}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.

$$a_{1}=\frac{2+1}{2}$$

Add 2 and 1 to get 3.

$$a_{1}=\frac{3}{2}$$

Assign a_1

$$a_{1}≔\frac{3}{2}$$
