Question

if the sum of 3 term of ap is 27 .than find the first terms​

Answer 1

Step-by-step explanation:

sum of n terms of an ap is (n/2)(2a+(n-1)d)

given the sum of 3 terms of ap is 27

then 27=(3/2)(2a+(3-1)d)

27= (3/2)(2a+2d)

27=(3/2)(2(a+d))

27=3(a+d)

(27/3)=a+d

a+d= 9

if you give total question I can solve totally

you given only half question so l solved only half question
