Problem

A knitting pattern for a shawl calls for 8

stitches in the first row. Each row after that

has 2 more stitches than the previous row.

The explicit rule ax = 8 + (k − 1)2 gives the

number of stitches in the nth row row.

Which of those sequences is a geometric sequence

It is given that the quadratic equation hx²-3x+k=0, where h and k are constants, has roots [tex] \beta \: and \: 2 \beta [/tex]express h in terms of k
