Geometric sequences and ! don’t have much time left, will mark you brainliest 1) which of the following describes the sequence 1, 1, 2, 3, 5, (explain) a) arithmetic b) geometric c) neither d) both 2) find a7, the 7th term, of the geometric sequence 1, 1/2, 1/4, 1/8, a) 1/16 b) 1/32 c) 1/64 d) 1/128 3) compare the quantity in column a with the quantity in column b. choose the best answer, column a the 4th term of the geometric sequence where a1=6 and r=5 column b the 4th term of the geometric sequence where a1=5 and r=6. a) the quantity in column a is greater. b) the quantity in column b is greater. c) the two quantities are equal. d) the relationship cannot be determined from the information given.
