Saraswathy  (10 years ago)

2*(2-1) + 2*3 => 2+6 = 8
3*(3-1) + 3*7 => 6+21 = 27
4*(4-1) + 4*5 => 12+20 = 32
5*(5-1) + 5*8 => 20+40 = 60
6*(6-1) + 6*7 => 30+42 = 72
7*(7-1) + 7*8 => 42+56 = 98

Ans : 98

98

2+3--> 2*(3+1) = 2*4 = 8
3+7--> 3*(7+2) = 3*9 = 27
4+5--> 4*(5+3) = 4*8 = 32
5+8--> 5*(8+4) = 5*12 = 60
6+7--> 6*(7+5) = 6*12 = 72

7+8--> 7*(8+6) = 7*14 = 98

harshal agrawal  (10 years ago)

2+3 = 2*(3+1)=8
3+7 = 3*(7+2)=27
4+5 = 4*(5+3)=32
i.e. first number is multiplied by sum of second number and (first number-1)
hence, 6+7 = 6*(7+5)= 72
similarly 7+8 = 7*(8+6) = 7*14 = 98ANS

lakshman singh  (9 years ago)

ANSWER is 98;
2*3+2=8; 3*7+6=27; 4*5+12=32; 5*8+20=60; 6*7+30=72;
so the series of no. which is added is 2 ,6,12,20,30
6-2=4; 12-6=6; 20-12=8; 30-20=10; x-30=12, x=42;
so 7*8+42=98;
