Question 560377
what is the next number in the arithmetic sequence 3, 11, 19, 29...
Are you sure the 29 is not supposed to be 27?
3+8=11+8=19+8=27
To solve you should first find the common difference.
d=t4-t3
d=27-19
d=8
plug it into the formula tn=t1+(n-1)d
t5=3+(5-1)8
t5=3+4(8)
t5=3+32
t5=32
3,11,19,27,32...
