The 3rd and 9th term of a G.P are 54 and 39366 respectively find the 6th term (b) the sum of the 4th and 7th term ( c) product of 2nd and 5th term
r^6 = 729, so r = ±3 and a=6
a6 = ±1458
a4+a7 = ±162 + 4374
a2*a5 = ar*ar^4 = 6^2 * ±243 = ±8748
a6 = ±1458
a4+a7 = ±162 + 4374
a2*a5 = ar*ar^4 = 6^2 * ±243 = ±8748
