Determine the third term of a geometrical progression whose first and second term are 2 and 14 respectively

Determine the third term of a geometrical progression whose first and second term are 2 and 14 respectively

Answer Details

1st G.P. = a =2
2nd G.P. = ar − 1 = 54
2(r) = 54
r = 54/2 = 27
r = 27
3rd term = ar2 = (2) (27)2
2 × 27 × 27
= 1458
