Question

If a,5,b,11 are 4 consecutive terms of A.p. Find possible values of a and b.

Answer 1

Answer:

GIVEN , A ,5,B,11

==> WE KNOW THAT SUM OF 1ST AND 3RD TERM BY 2 IS EQUAL TO SECOND TERM

SO, ==>A+B/2 = 5

==> A+B= 10 ...(1)

SIMILARLY ,

===> 5+11/2 = B

==>16/2 = B

==> B = 8

SO, A+B = 10

==> A+8 = 10

==> A = 2

SO, A = 2 , B = 8
