The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.
We will use demonstration of recurrences<span>1) for n=1, 10= 5*1(1+1)=5*2=10, it is just
2) assume that the equation </span>10 + 30 + 60 + ... + 10n = 5n(n + 1) is true, <span>for all positive integers n>=1
</span>3) let's show that the equation<span> is also true for n+1, n>=1
</span><span>10 + 30 + 60 + ... + 10(n+1) = 5(n+1)(n + 2)
</span>let be N=n+1, N is integer because of n+1, so we have
<span>10 + 30 + 60 + ... + 10N = 5N(N+1), it is true according 2)
</span>so the equation<span> is also true for n+1,
</span>finally, 10 + 30 + 60 + ... + 10n = 5n(n + 1) is always true for all positive integers n.

Correct option is E, like legends about other naval heroes, is
It does this by contrasting "this legend" with "legends about other naval heroes," so avoiding the mistake of the original. There is an unreasonable comparison in option (A). "This legend" is contrasted with "other naval heroes."
There is an agreement mistake in option (B). For the single subject "this legend," the plural verb "are" is used. There is an unreasonable comparison in option (C). "This legend" is contrasted with "other naval heroes." Choice (D) has an agreement mistake.
For the single subject "this legend," the plural verb "are" is used. Option E can be used to rewrite the sentence's highlighted portion. By contrasting "this legend" with "legends about other naval heroes," the inaccuracy is fixed. As a result, choice E is the right answer.
