1,5,25,61.....<br>What's following number?

Lana71 [14]

Given:

1,5,25,61.....

To find:

The following number.

Solution:

We can see a pattern in the given sequence.

$(-1)^2+(0)^2=1+0=1$

$(1)^2+(2)^2=1+4=5$

$(3)^2+(4)^2=9+16=25$

$(5)^2+(6)^2=25+36=61$

Using this pattern the next term is the sum of squares of 7 and 8.

$(7)^2+(8)^2=49+64=113$

Therefore, the next number is 113.

If f(x)= 15x+7x and g(x)= x^2-5x, find (f+g)(x)

cupoosta [38]

Answer:

(f+g)(x) = x^2 +10x +7

Step-by-step explanation:

(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)

= x^2 +x(15 -5) +7

= x^2 +10x +7
