Step-by-step explanation:
tn = {6 + (n-1) (-3)} ---(1)
For the other A.P,
tn = {2 + (n-1) (-2)} ---(2)
By the problem (1) and (2) are equal
So 6 - 3n + 3 = 2 - 2n + 2
OR n = 5
Let us verify the same
6, 3, 0, -3, -6
2, 0, -2, -4, -6
Yes both have -6 as the fifth term.

Step-by-step explanation:
tn=(6+(n-1) (-3))---(1)
for other AP
tn=(2+(n-1) (-2) )---(2)
By the problem (1)and (2) are equal
so 6-3n+3=2-2n+2
or n=5
