Question

T4+t6=24,t8+t10=44,value of d---

Answer 1

Step-by-step explanation:

T4=a+(4-1)d

T6=a+(6-1)d

T4+T6=24

a+3d+a+5d=24

2a+8d=24

a+4d=12...........(1

T8=a+(8-1)d

T10=a+(10-1)d

T8+T10=44

2a+16d=44

a+8d=22.........(2

(2)-(1)

a+8d=22

-(a+4d=12)

_______

a+8d=22

-a-4d=-12

_______

4d=10

d=10/4=2.5
