Answer:
I am giving 57th question , answer :-
Mark it as brainlist answer
Step-by-step explanation:
according to question a=200 , D= 40 , we have to find a30 ,
a30 = a+29d
a30= 200+(29×40)
A30= 200+1160
A30=1360
Answer:
40. a¹⁵=3+2(a⁷)
a+14d=3+2(a+6d)
a+14d=3+2a+12d
a+14d-2a-12d=3
-a+2d=3___1
a⁷=41
a+6d=41.__2
equation 2-1
a+6d=41
-a+2d=3
_______
8d=44
_______
d=44/8
-a+2d=3
-a+2(44/8)=3
-a+44/4=3
-a+11=3
-a=3-11
-a=-9
a=9
an=a+(n-1)d
a¹⁵=9+(15-1)44/8
a¹⁵=9+14(44/8)
a¹⁵=9+77
a¹⁵=86
