Answer 1

Answer:

Step-by-step explanation:

A16=5(A3)

A+15D=5(A+2D)

A+15D=5A+10D

-4A=-5D

A=5D/4.....(1)

NOW,

A10=41

A+9D=41

PUTTING VALUE OF' A'

5D/4+9D=41

5D+36D=165

41D=164

D=4(PUTTING IN EQ 1)

WE GET,

A=5

NOW,

S15=15/2[2(5)+(15-1)4

15/2(10+56)

15/2*66

15*33

495 IS THE ANSWER
