Question

the common difference of two arthematic progression is equal. if the first term of first arthematic progression is 6 and the first term of second arthematic progression is 10 then the difference of 5th term of these arthematic progression is​

Answer 1

Answer:

4

Step-by-step explanation:

Here,

Let a1, a1 + d, a1 + 2d, a1 + 3d ---- a1 + 5d be 1st AP and a2, a2 + d, a2 + 2d, a2 + 3d ----- a2 + 5d be 2nd AP,

Now,

a1 = 6, a2 = 10, d1 = d2

Difference of 5th terms = (a2 + 4d2) - (a1 + 4d1)

                                       = 10 + 4d - 6 -4d

                                        = 4
