Answer:
Use the formula for Arithmetic only if it is Arithmetic: a1+ (n-1)d
a represents the first number in the sequence, n represents the number, and d represent common difference
Use the formula for geometric sequence: an=a1r the exponent of r to n-1
an represents the nth term you are trying to find, a1 represents the first number, r represents the common ratio, and n-1 is just the nth term minus 1.
Once you figure out if the sequence is arithmetic or geometric you one of those formulas.
It’s 7 because you round it
First term is 13m with factors 13 and m
second term is -2n with factors -2 and n
Answer:
73.3
Step-by-step explanation:
7%=7÷100=0.07 ×60=4.2
15%=15÷100=0.15×60=9
add you answers to 60 and to should get 73.2
