Question

if an represent nth term of ap
a2+a5-a3=10&a2+a9=17 find the first term and common difference​

Answer 1

Step-by-step explanation:

a2 + a5 -a3 = 10

a+d+a+4d-a-2d= 10

2a+3d= 10_eq1

a2+a9= 17

a+d+a+8d= 17

2a+9d= 17_eq2

sub eq 1 and 2

-6d= -7

d= -7/-6

d= 7/6

2a+3(7/6)=10

2a+7/2=10

4a+7/2=10

4a+7=20

4a= 20-7

4a=13

a=13/4
