1.

4. Write the first five terms of the G.P. where nth termis given as:521(i) 4.39-12n]

Answer»

(1) nth term of GPTn = 4.3^n-1

Thus,T1 = 4.3^1-1 = 4*1 = 4T2 = 4.3^2-1 = 4*3 = 12T3 = 4.3^3-1 = 4*9 = 36T4 = 4.3^4-1 = 4*27 = 108T5 = 4.3^5-1 = 4*81 = 324

(2) nth term of GPTn = 5^n-1/2^n+1

Thus,T1 = 5^0/2^2 = 1/4T2 = 5^1/2^3 = 5/8T3 = 5^2/2^4 = 25/16T4 = 5^3/2^5 = 125/32T5 = 5^4/2^6 = 625/64
