## anonymous one year ago The partial sum of the first 6 terms of the arithmetic sequence with a1 = -6 and d = 4 is 24. True or False

1. Nnesha

do you know the formula to find other 5 terms of the sequence ?

2. anonymous

i think i have it but im not sure how to type it here haha

3. Nnesha

oh okay $\huge\rm a_n = a_1+(n-1)d$ d= common difference a_1=first term n= number of term so to find 2nd term substitute n for 2

4. anonymous

so i just plug the a1 and d into that equation and add them, correct?

5. Nnesha

a_1 = -6 d=4 so plug them into the equation solve the parentheses first and then multiply by 4(d) and then add with -6

6. Nnesha

like for 2nd term $\huge\rm a_2 = -6+(\color{ReD}{2}-1)4$ solve the parentheses first 2-1=1 -6+1(4) -6+4 =-2 so 2nd term is -2 find other 4 and then combine them
