Question

if 5+6=371 6+8=860 7+5=251 then 8+9=?

Answer 1

Answer:

811

..................

Answer 2

8 + 9 = 1179.2

Step-by-step explanation:

The given series pattern is

5 + 6 = 371,  6 + 8 = 860,  7 + 5 = 251 then 8 + 9 = ?

The given series are in the pattern = x₁ + x₂ = y

and $y=\frac{[-5978+(249)(x_1)+(1098)(x_2)]}{5}$

(1) 5 + 6 = 371

=     $\frac{[-5978+(249)(5)+(1098)(6)]}{5}$  

= 371

(2) 6 + 8 = 860

= $\frac{[-5978+(249)(6)+(1098)(8)]}{5}$

= 860

(3) 7 + 5 = 251

= $\frac{[-5978+(249)(7)+(1098)(5)]}{5}$

= 251

(4) 8 + 9 =

y = $\frac{[-5978+(249)(8)+(1098)(9)]}{5}$

= 1179.2

Hence, the answer would be 8 + 9 = 1179.2
