Complete the sequence given below:
2,2,5,13,28,?

The next term is 52

Step-by-step explanation:

...

52

Step-by-step explanation:

Answer for this question as follows

2–2=0

5–2=3

13–5=8

28–13=15

As we observe the difference of the difference is

3–0=3

8–3=5

15–8=7

Here the differnce is increasing by two

X-15=7+2=9

X=24

So the required answer is 28+24=52

b. b < 1 might be the correct answer

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
