Answer 1

4)4633

Step-by-step explanation:

The required answer is 771

Step-by-step explanation:

11 is obtained by :

last number × 2 + 3

= 4 × 2 + 3

= 11

37 is obtained by :

last number × 3 + 4

= 11 × 3 + 4

= 37

153 is obtained by :

last number × 4 + 5

= 37 × 4 + 5

= 153

771 = last number × 5 + 6

                       = 153 × 5 + 6

                       = 771

so next number will be =771×6+7

=4626+7=4633

Hope it helps.

Answer 2

Answer:

4 * 2 = 8 + 3 = 11

11 * 3=33 + 4= 37

37*4= 148+5 =153

153*5=765 +6 =771

771 * 6= 4626+7 = 4633

You need to keep on adding 1 and multiply

like 4 * 2 =8

then 11 * (2+1) = 11*3=33

then same applies when you add

like 8+3=11

33+(3+1)=33+4=37
