Answer 2

Answer: 31 terms

Explanation:

nth term of AP1 is given by,

R = 3 + (n-1) *4

mth term of AP2 is given by,

r = 4 + (m-1) *3

For R to equate to r,

3 + (n-1) *4 = 4 + (m-1) *3

3 + 4n - 4 = 4 + 3m - 3

4n - 1 = 3m + 1

4n - 2 = 3m

n = (3m+2)/4

For m = 2,6,10,14... we have corresponding value of n = 2,5,8,11...

Now, number of terms in AP2 = 125

Using the above sequence of m,

2 + (v-1) *4 = 125

4v - 2 = 125

v = 127/4

v = 31.75

v = 31 terms
