PZ HELP I HAVE A DEADLINE Write a recursive formula for finding the nth term of each arithmetic sequence. 15.75, 14.25, 12.75, …

a1 = 15.75, an = an – 1 + 1.5

a1 = 12.75, an = an – 1 – 1.5

a1 = 11.25, an = an – 1 + 1.5

a1 = 15.75, an = an – 1 – 1.5

 D. a1=15.75,an = an -1 -1.5

Step-by-step explanation:

Sorry about the no explanation, but the answer is correct.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

step-by-step explanation:

a and d
