Answer:
Step-by-step explanation:
Welcome!
Given that:
From the given sequence 2+3=8, 3+7=27, 4+5=32, 5+8=60, 6+7=72, 7+8=, What number comes next?
First Way:
(2 +3 - 1) × 2 = 08
(3 + 7 - 1) × 3 = 27
(4 + 5 - 1) × 4 = 32
(5 + 8 - 1) × 5 = 60
(6 + 7 - 1) × 6 = 72
(7 + 8 - 1) × 7 = 98
Second Way:
2*(3 + 1) = 08
3*(7 + 2) = 27
4*(5 + 3) = 32
5*(8 + 4) = 60
6*(7 + 5) = 72
7*(8 + 6) = 98
Third Way:
2*1 + 3*2 = 02 + 06 = 08
3*2 + 7*3 = 06 + 21 = 27
4*3 + 5*4 = 12 + 20 = 32
5*4 + 8*5 = 20 + 40 = 60
6*5 + 7*6 = 30 + 42 = 72
7*6 + 8*7 = 42 + 56 = 98
