What is the sum of the arithmetic sequence 8, 15, 22 …, if there are 26 terms?

bixtya [17]

For the regular sequence 1, 2, 3, ..., $n$ , then sum is
$\frac{n(n+1)}{2}$

If we multiply each number by 7 (7, 14, 21, ...), then the sum is
$\frac{7n(n+1)}{2}$
and if we add 1 to each number (8, 15, 22, ...) then the sum is
$\frac{7n(n+1)}{2}+n$

We have $n=26$ terms, so the sum is:
$\frac{7(26)(27)}{2}+26$
$=7(13)(27)+26$
$=91(27)+26$
$=2457+26$
$=2483$

$\huge\text{Hey there!}$

$\large\text{We cannot do much of nothing because we don’t have all the information}\\\large\text{to solve.. so we can just simply do process of elimination until we fully find}\\\large\text{the ANSWER you are trying to look for.}$

$\large\text{Given equation: 25b - 14b}\\\large\text{COMBINE your LIKE TERMS}\\\large\text{\underline{25b - 14b} = 11b}\\\large\text{So, we are looking for an equation that gives us \bf{11b}}$

$\large\text{Option A.}\downarrow\\\large\text{b(25 - 14)}\\\large\text{DISTRIBUTE: b(25) + b(-14)}\\\bullet\large\text{ Reverts to: 25b - 14b (our ORIGINAL EQUATION) so this can be}\\\large\text{equal to 11b}\\\\\large\text{Option A. could POSSIBLY be your ANSWER}$

$\large\text{Option B. }\downarrow\\\large\text{b(25 + 14)}\\\large\text{Distribute}\\\large\text{25(b) + 14(b)}\\\large\text{It DOES NOT revert to the original equation. It gives us: 25b + 14b}\\\large\text{If we COMBINE your LIKE TERMS in that equation. We would get: 39b}\\\large\bf{39b \neq 11b}\\\\\large\text{Option B is NOT your ANSWER}$

$\large\text{Options C and D CANNOT be your answers because Option C. is}\\\large\text{-11b and Option D. is -39b}$

$\boxed{\boxed{\large\text{To sum it all up, your ANSWER is: \bf{Option A. b(25 - 14)}}}}\huge\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
