Product of 5 numbers in geometric progression = 32
Calculation:
Let the five numbers in geometric progression be ar2, ar, a, a/r, a/r2
⇒ ar2 × ar × a × a/r × a/r2 = 32
⇒ a5 = 32
⇒ a5 = 25
Powers are same so equating the bases
a = 2
a is the third number of geometric progression
∴ The third number is 2
