**Steve**, Tuesday, April 10, 2012 at 3:33pm5+9x - (4+7x) = 1+2x

a = 4+7x

d = 1+2x

T10 = a+9d = 4+7x + 9(1+2x) = 13+25x

T21 = a+20d = 4+7x + 20(1+2x) = 24+47x

**Mfuno**, Sunday, January 19, 2014 at 3:57pmT10 = 4 + 7x +(10-1)1+2x

= 4 + 7x +9(1+2x)

= 4 + 7x +9+18x

= 13+25x

T21 = 4+7x +(21-1)1+2x

= 4+7x +20(1+2x)

= 4+7x +20+40x

= 24+47x
