What is a21 of the arithmetic sequence for which a7=−19 and a10=−28? A. -35 B. 35 C. -58 D. -61

shepuryov [24]

Answer:

a21 = -61

Step-by-step explanation:

$a_{n}=a_{1}+(n-1)d$

$-19=a_{1}+(7-1)d$

$-28=a_{1}+(10-1)d$ (subtract to eliminate a₁)

9 = -3d

d = -3

-19 = a₁ + (6)(-3)

-1 = a

a21 = -1 + (21 - 1)(-3)

= -61
