Answer:
use the formula sn= n(a1+an)/2
Step-by-step explanation:
2982=28(228+an)/2
5964=28(228+an)
5964/28=228+an
213=228+an
an=-15(last term)
to find difference use formula
an = a+(n-1)d
-15=228+(28-1)d
-243=27d
d=-243/27
d=-9
arithmetic sequence can be found be keep on subtracting 9 from 228
hence the arithmetic sequence is
228, 219, 210, 201, 192, 183, 174........-15
answer: 2 × 2 × 2 × 2 × 2 = 32
Step-by-step explanation:

I think its shear, because that is the only one in which the shape actually changes shape and size
Scientific notation is used to write really large numbers, or really small numbers using less digits. For example:
1. Earth's distance from the sun 150,000,000 kilometers. We can rewrite this in scientific notation as 1.5 x

2. The length of a skin cell is 0.00003 meters. We can rewrite this in scientific notation as 3.0 x

3. The world population is about 7,000,000,000. We can rewrite this in scientific notation as 7 x
