Answer:
the is your answer
the 50term is 149.
the sum of 50term is 3775.
Step-by-step explanation:
a=t1=2,t2=5
d= t2-t1
d=5-2
d=3
tn=a+(n-1)d
t50=2+(50-1)3
t50=2+(49)3
t50=2+147
t50=149
therefore the 50term is 149
Sn=n÷2[2a+(n-1)d]
S50=50÷2[2×2+(50-1)3]
S50=50÷2[4+(49)3]
S50=50÷2[4+147]
S50=50÷2×151
S50=25×151
S50=3775
therefore the sum of the 50term is 3775.
