The sum of 555 consecutive integers is 270270270. What is the second number in this sequence?
Simora [160]

The second number in the sequence will be 53.

<em><u>Explanation</u></em>

The <u>difference between any two consecutive integers is always 1</u>.

Suppose, the five consecutive integers are:  n,  n+1,  n+2,  n+3 and  n+4

Given that, their sum is 270. So, the equation will be......

n+(n+1)+(n+2)+(n+3)+(n+4)=270\\\\ 5n+10=270\\\\5n=270-10=260\\ \\ n=\frac{260}{5}=52

Thus, the second number in the sequence will be:  n+1= 52+1=53

2.) What amount presently must be invested earning 5.25% compounded continuously
julsineya [31]

The amount A resulting from a principal amount P being invested at rate r compounded continuously for time t is given by

... A = P·e^(rt)


FIll in your given values and solve for P.

... 25000 = P·e^(0.0525·12) = P·e^0.63

... P = 25000/e^0.63 ≈ 13314.80 . . . . . divide by the coefficient of P


The amount that must be invested is $13,314.80.
