WILL GIVE BRAINLIEST The sequence 7 21 63 189......shows the number of jumping jacks justin did each week, starting with the fir
vovangra [49]

A

this is a geometric sequence since there exists a common ratio r between the terms

r = \frac{21}{7} = \frac{63}{21} = \frac{189}{63} = 3

B

to obtain the next term in the sequence multiply the previous term by 3

a_{n+1} = 3 a_{n} ← recursive rule

C

the n th term of a geometric sequence is

a_{n} = a_{1} r^{n-1}

where a_{1} is the first term in the sequence

a_{n} = 7 × 3^{n-1} ← explicit rule
