Question

The sum of 4th and 8th term
of on AP is 24 and 6th and
and 2th term is 44 find the
Sum of first 10 term​

Answer 1

Step-by-step explanation:

For the sum of 4th and 8th term

a+(4-1)d + a+(8-1)d=24

a+3d+a+7d=24

2a+10d=24

a+5d=12......... 1

Again, a/q

a+(6-1)d + a+(2-1)d=44

a+5d+a+d=44

2a+6d=44

a+3d=22..........2

Now subtracting eq2 from eq1

a+5d-a-3d=12-22

2d=-10

d=-5

So, a=-37

Now u can find first 10 terms
