Answer:
The number of blocks in the nth figure will be (3n + 1).
Step-by-step explanation:
See the attached figure where few arrangements are there.
The number of blocks in the first arrangement is (3 + 1)
Now, the number of blocks in the second arrangement is (3 × 2 + 1)
Again, the number of blocks in the third arrangement is (3 × 3 + 1)
So, the pattern says that the number of blocks in the nth arrangement will be (3 × n + 1) = (3n + 1) (Answer)
R+p=28 → p=28-r
2r+28-r=43 → r=15
p=28-15=13

Here,
n = 11
mean = 7
Standard Deviation (σ) = 3
S.E. = ?
We know that,
S.E. = σ/
S.E. = 3/
∴ S.E. = 0.905 Ans.
