Question

What is the Sequence of 9,12,7,105? with solutions

Answer 1

Answer:

417

Step-by-step explanation:

9,12,7,105?

these are the terms of the sequence

(37n³−230n²+437n−226 )/2

n = 1

(37 - 230 + 437 - 226 )/2 = 18/2 = 9

n = 2

(37*8 - 230*4 + 437*2 - 226 )/2

= 37*4 - 230*2 + 437 - 113

= 148 - 460 + 324

= 12

n = 3

(37*27 - 230*9 + 437*9 - 226 )/2

= 7

n = 4

(37*64 - 230*16 + 437*4 - 226 )/2

= 105

n = 5

(37*125 - 230*25 + 437*5 - 226 )/2

= 417
