Write the explicit formula for the
following geometric sequence:
3, -12, 48, -192, ...

9514 1404 393

  an = 3(-4)^(n-1)

Step-by-step explanation:

The explicit formula for a geometric sequence with first term a1 and common ratio r is ...

  an = a1(r^(n-1))

The given sequence has a first term of 3 and a common ratio of -12/3 = -4. The explicit formula is ...

  an = 3(-4)^(n-1)

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
