Question

If 3k-3, 3k + 3 and 4k + 4 are three
AP So wath is value of (k)

Answer 1

Since , the given terms is in AP,

It means that a3 - a2 = a2 - a1

a1 = 3k-k

a2 = 3k+3

a3 = 4k + 4

a3 - a2 = a2 - a1

or, 4k + 4 - (3k + 3) = 3k + 3 - ( 3k - 3)

or, 4k + 4 - 3k - 3 = 3k + 3 - 3k + 3

or, k + 1 = 0k + 6

or, k + 1 = 6

or, k = 6 - 1

or, k = 5 ANSWER .
