A) 3n - 7
B) 3n + 7
C) 3n +1
D) 3n ? 1
Correct Answer: C
Solution :
The general term of an arithmetic progression is given by \[={{2}^{2}}\times {{3}^{2}}\times 5\times 7\times 11\times 13=180180\]where 'a' is the first term and 'd' is the common difference. Here, a = 4 and \[\therefore \] \[H.C.F.=\frac{\text{Product of the numbers}}{L.C.M.}\]. \[\text{5474}=\text{2}\times \text{7}\times \text{17}\times \text{23}\]Then\[\text{9775}={{\text{5}}^{\text{2}}}\times \text{17}\times \text{23}\]term \[\text{1173}0=\text{2}\times \text{3}\times \text{5}\times \text{17}\times \text{23}\] \[\therefore \]
