Answer:the pages will come on the first is 210
Explanation:
Since we have given that two pages that face each other in a book
i.e. they must be consecutive to each other
so, let the first page number be x
and the second page number be x+1
According to question,

2x=421 -1
2x=420

So, the pages will come on the first is 210
Answer:
45
Step-by-step explanation:
Since this is only three terms
Find the three terms and add
j=1 3(1)^2+1 = 3+1 =4
j=2 3(2)^2+1 = 3(4)+1 =13
j=3 3(9)^2+1 = 27+1 =28
The sum is 4+13+28 =45
