Jane has a checkbook balance of $68.00. she then writes two checks, one for $5.00 and one for $62.50. she
determine her new balance. which of the following is the correct series of keys she should press?
o a. [68] [+] [75] (5) 6 (62,50] ]
o b.[on/c] [68] [6] [75] [f[5] [62.50] [
o c. [68] [+] [75] [62.50] 15]
o d. [on/c] [68] [5] [62.50] [+[75] f]

b. astronomers

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
