Q1.Find the vale of k If 2k+1,6,3k+1 are in AP
O
a.1
O b. 3
C. 2
O d. 5​

Answer 1

Answer:

k = 2

Step-by-step explanation:

d = a2 - a1

so , 6 - 2k - 1 = 5 - 2k _____ eq 1

d = a3 - a1

so , 3k + 1 - 6 = - 5 + 3k _____eq2

solve eq1 and eq2 are equal

then , 5 - 2k = 3k - 5

5 + 5 = 3k + 2k

5k = 10

k = 2
