Let: \large{\text{Let:}}

a 1 = 15000 \large{{ a }_{ 1 }=15000}

d = 2000 \large{d=2000}

n = ( 2017 2000 ) + 1 = 18 \large{n=(2017-2000)+1 =18}

Solution: \large{\text{Solution:}}

a n = a 1 + ( n 1 ) d = 15000 + ( 17 ) ( 2000 ) = 49000 \large{a_{ n }=a_{ 1 }+(n-1)d\\ \quad =15000+(17)(2000)\\ \quad = 49000}


His annual salary in 2017 will be $ 49000 \large{\therefore \text{His annual salary in } 2017 \text{ will be } \$49000}

so how is the answer 5.
