7*8=56(+42=30+12)

∑ c(n-1)+d(n) - (∑ c(n-1)+d(n) - ∑ a(n-1)+b(n)) = u

Deleten = 2 n = 3

2(1) + 3(2) = 8 = u

3(2) + 7(3) = 27

4(3) + 5(4) = 32

5(4) + 8(5) = 60

6(5) + 7(6) = 72

7(6) + 8(7) = 98

DeleteThought exactly like that, although without this part:

"∑ c(n-1)+d(n) - (∑ c(n-1)+d(n) - ∑ a(n-1)+b(n)) = u

n = 2 n = 3"

... I'm just inthe 9th grade (from Portugal).

Its 98

DeleteAdd both numbers

then multiply the result with first number

and then subtract the first number with the result

therefore: 7+8 = 15

then 15 X 7 = 105

then 105 - 7 = 98

98??

this is the awnser 4 sure cause i know alot about math i know it all for this math problem for the harest and easyest cause this is a*a=3 then8*8=64cause if you add subtract divide multiply you get the problem and awnser ther is the awnser to the math problem this is realy easy because it is all in your bloode and brain i have the right awnser.......Thank you for reading this

= (b+o) * a where

ReplyDeleteb = 2nd number

o = order that the equation appears in or (a-1)

a = first number

answer = 98.

O thanks!

ReplyDeleteselvakumar (a+b)-1*a

ReplyDeleteits 98

ReplyDeletethe answer is 98

ReplyDeletethe formula is :

simplified to :

a(a+b-1)

I enjoyed it!

ReplyDeleteso

7+8 => 56 + 42 => 98

(ab)+(a(a-1))=R

ReplyDeleteThough I don't feel any accomplishement for finding an answer in less than 10 mins. Random pattern finding is what solves these type of problems.

ReplyDelete98, (a+b)*n+b , where n is the sequence no of equation.

ReplyDeleteIts 98

ReplyDelete2 + 3 = 8 : 2* (2+3-1)

ReplyDelete3 + 7 = 27 : 3* (3+7-1)

.

.

7+ 8 = 98 : 7*(7+8-1)

2*(3+1)=8

ReplyDelete3*(7+2)=27

ReplyDeletea*b+(a-1)*a....

ReplyDelete98 that's quite simple

ReplyDeletea(a+b)-a,answer98

ReplyDelete{(a*b)+i*a},where i=1,2,3....

ReplyDelete98

ReplyDelete98

ReplyDeletebcoz

2+3=2*[3+(2-1)=8

3+7=3*[7+(3-1)=27

4+5=4*[5+(4-1)=32

5+8=5*[8+(5-1)=60

6+7=6*[7+(6-1)=72

Therefore

7+8=7*[8+(7-1)]=98

x+y=x[y+(x-1)=x^2+xy-x

since when 2+3=8? this is a wrong equality from the very beginning and against all math theories. 2+3=5 and therefore 7+8=15

ReplyDeletethis is the answer.. :)

2 * 3 + 2 =8

ReplyDelete3 * 7 + 6 =27,

4 * 5 + 12 =32,

5 * 8 + 20 =60,

6 * 7 + 30 =72,

7 * 8 + 42 = 98

you guys are smart..

ReplyDeleteThere are lots of solutions to this. One set is of the form:

ReplyDeletef(x,y)=(1-n)x^2-2ny^2+(3n+1)xy-(12n+1)x+13ny+11n

where n=0,1,2,3,...

if n=0 then f(x,y)=x^2+xy-x which produces f(7,8)=98

if n=1 then f(x,y)=-2y^2+4xy-13x+13y+11 so f(7,8)=120

continue to get 142,164, 186,....
