In a certain sequence of numbers, each term after the first term is found by multiplying the preceding term by 3 and then subtracting 2 from the product. If the third term of the sequence is 55, what is the first term of the sequence?

A. 5
B. 6
C. 7
D. 8
E. 9


a2= (3*a1)-2--- (1)
a3=(3*a2)-2

55=(3a2)-2
a2=19

and solving in eqn 1 will give a1 as 7 option C
