MARK ME THE BRAINLIEST......


t10=46
a+9d=46---------eq.1

t5+t7=52
a+6d+a+4d=52
2a+10d=52
Dividing each one by 2,
a+5d=26-----eq.2

Now,
Subtracting eq.2 from eq.1

a+9d=46
- a+5d=26
________
4d=20

therefore, d=5

Substituting value of d in eq. 1
a+9d=46
But d=5,
a+9*5=46
a=1

therefore,
a=1 and d=5

A.P,
a,a+d,a+2d,........
1,1+5,1+2×5,....
1,6,11,.......
Is the A.P.
