first term of GP a = x²

common ratio,

r = x / x²

r = 1 / x

an = ar {}^{n - 1}

a31 = x {}^{2} ( \frac{1}{x} ) {}^{31 - 1}

a31 = x  {}^{2}( \frac{1}{x} ) {}^{30}

a31 = x {}^{2}  \frac{1}{x {}^{30} }

a31 =  \frac{1}{x {}^{28} }

a31 = x {}^{ - 28}

Hope the solution is clear to you!!

Step-by-step explanation:

r= x/x² = 1/x

N = 31

a= x²

t31=ar*n^-1

t31 = x²*1/x^31-1

t31 = 1/x^28

ans : 1/x ^28
