Answer: 19
Step-by-step explanation:
The answer is 19 because, if n=5 then we have to divide 45 by 5. 45 divided by 5 equals 9. and to make sure we can multiply 9 and 5 and that equals 45. So now its saying what is 9 plus 10 and that equals 19. Just to make sure we can subtract 19 by 10 or 9 and if we do eitheer one they both equal 19.

Answer:
186
Step-by-step explanation:
Answer:
C a1= -2
an = an-1 +3
Step-by-step explanation:
an = -2+ (n-1)3
What is the first term? Let n=1
a1 = -2 + 0*3
a1 = -2
The difference between the terms is +3 (coefficient on (n-1))
The second term is the first term +3
The third term is the second term plus 3
The next term is the previous term +3
so an = an-1+ 3
