a, b, c, d are in G. P.
So, their ratios will be equal.
b^y = a^x = d^w = c ^z = ¥
a = ¥ / x, b = ¥ / y, c = ¥ / z , d = ¥ / w
b² = ac and c² = bd
( ¥ / y )² = ¥ / x * ¥ / z
( ¥ / y )² = ¥² / ( x z )
¥² / y² = ¥² / xz
1 / y² = 1 / xz
Similarly,
1 / z² = 1 / yw
So, 1 / x, 1/ y, 1/ z and 1 / w are in A. P.

A spontaneous reaction by definition is a reaction that occurs without the intervention o the outside. For example, when ice melts at 25∘C it will melt spontaneously. Water will freeze spontaneously at 0∘C . In the presence of air and moisture, iron will rust spontaneously.
