SOLUTION
An infinite series is the sum of an indefinitely many numbers related in a given way. That is the addition of such number is continuos. So our answer should be between
B) 2 − 6 + 18 − 54 + . . . and
C) 3, 13, 23, 33, . . .
But, looking at both, C) is a sequence showing ordered list of numbers.
Hence B) is a showing series showing sum of a list of numbers or showing multiplication pattern.
Therefore, the correct answer is option B.
