What is the explicit formula for this sequence -5, -3,-1,1,

These numbers are increasing by 2 for each n.

The explicit formula for a sequence should read:

an = a1 + d(n – 1)

If d=2, the explicit formula would read:

an = a1 + 2(n – 1)

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
