Question

If(3m-1),(3m+1)&(5m+1) are first three terms of an AP then find the value of m

Answer 1

Answer:

m = 1

Step-by-step explanation:

If numbers are in ap then their common difference (d) is same.

==: (3m + 1) - (3m - 1) = (5m + 1) - (3m + 1)

==: 3m + 1 - 3m + 1 = 5m + 1 - 3m - 1

==: 2 = 2m

==: m = 1
